What Is An Isotope?

What Is An Isotope?Chemistry is a branch of science which deals with the study of elements. There are a number of substances in the world which are element types and belong to different element groups. Scientists of today are mainly interested in the study of elements that are isotopes and isotope composition. In their research, scientists are studying the properties of elements, what they contain and how it is synthesized.From the study of isotopes, scientists have already recognized many elements that have no trace in the atmosphere of earth. Such elements are known as 'strontium 90' helium-3'. Such isotopes are rare and rarer element and are important in our daily lives. Their use can be found in computers, mobile phones, hi-fi equipment, all-terrain vehicles, scientific instruments and air-cooled power plants. In most of the cases, these special isotopes are used in powering modern day electronics.Other than isotopes, there is also another type of isotopes - meso- and para- isoto pes. These isotopes are not found in nature but are created artificially in laboratories. Scientists do study the use of these isotopes. They are used in spaceflight to achieve higher orbits and reaching the International Space Station in order to conduct researches in the field of science and research.There are also a lot of other isotopes available in the market. The existence of them is actually a myth. All these isotopes are false as well. They are not authentic isotopes. It is true that they have some use, but they are of no use to mankind in general.Since so many types of isotopes exist, it is necessary to study each of them individually. In addition, isotopes of radioactive elements are also used in the laboratory. The presence of radioactive elements in a matter indicates that the atoms of the matter are unstable and the atoms are unstable in the presence of such isotopes.In order to classify isotopes into an element, a group is made. It is possible to use different standard s for classifying these isotopes. According to the standards, the basis for classification is the presence of additional forms of carbon and oxygen. In addition, it is found that the isotopes are heavier than the original atom. As a result, they are classified into a separate element.Iso-6 and P-22 are some of the isotopes of carbon that are identified as unique among all other carbon isotopes. However, they are not as rare as other isotopes and it is more common than the other isotopes. These isotopes were discovered by chance while analyzing the composition of rocks that were given to German scientist Emil Freund by some Chinese workers.

How to Balance Grades, a Social Life, and Sleep in College

How to Balance Grades, a Social Life, and Sleep in College Its the classic saying that every college student is familiar with Good grades, a social life, and enough sleep in college, you can only pick two. Getting a good education is of course the primary reason for attending college, but the social scene appeals to many students as well. However, the great determination and time it takes to maintain a good GPA is often underestimated by incoming freshmen, and balancing that academic life with the desired social life takes some discipline. Developing that skill is yet another time-consuming process, so where does that leave students with getting some shut-eye? Exactly. It would seem that most students lean toward picking the first two: good grades and a social life. This plan of execution never lasts long though because lets face it as humans, we need our sleep. We literally wont be able to function without a substantial amount of it. And realistically, how are you going to be able to study well enough to get an A on that exam while your brain is deprived of rest? Or how can you embark on these social gatherings when you are completely lacking energy? Students like to believe theyre tougher than that, but you cant fight biology; the body requires sleep. Here is some great info on theimportance of sleepthat you may want to check out. After accepting the importance of sleep, this popular phrase tells students they must choose between having fun and having As. Is this really reasonable? It shouldnt have to be a choice, but the time both of these activities take up sure makes it seem that way. Being fresh to the college scene, a new student may put their social life first on the priority list and believe they can coast their way through their schoolwork. The difficulty in your academics will ultimately depend on your major, but either way, this method wont fly. You cannot breeze through college assignments and tests. They all require adequate preparation that cannot be underestimated, so thinking you can beat the system will not serve you well. Here are some great tips on how to choose your extracurricular activitiesthat you may find useful. Yet, you should also take comfort in the fact that you wont need to be spending hours on end at the library every single night from Freshman Welcome Week through graduation. That would just be ridiculous, and its unheard of. Unless you go through some very strange scheduling scenario with a very poor academic advisor, you should never have a semester where every single class is a torturous battle one-hundred percent of the time. You will have killer classes, you will have regular classes, and you will hopefully have a couple of easy classes. The point is that college academics require intense studying and time, but not all of the time. There is no reason you cant have a social life as well. If it were impossible, that wouldnt be one of the favorite aspects of college you hear passed down from alumni. Now, some people do spend too much time on the social scene and end up with disappointing grades, but that is because they may not understand how to manage it well. It is important that you know how to successfully manage your various priorities. Keep a good balance of everything and don't let either side overwhelm you. After all, extracurricular activities can boost college success! So what does it all come down to? Is it impossible to have it all? The trick is to balance and rotate them accordingly. You can have it all, but not always excessively and not always at the same time. In the end, allow yourself time in your head (yes, another time-consuming task, but this is what college is!) to make thoughtful and smart decisions regarding each of these areas and things will work out just fine.

Thesis Writing English Writing Online Tutorpace

Thesis Writing English Writing Online Tutorpace A thesis is a statement placed as a premise in an argument and it should sum up what the essay is about. A good thesis statement contains a part which the writer desires to argue and also states how it is going to be argued in a succinct manner. Usually the introduction is closed with the thesis statement in short essays. The thesis should not be a question or a list of facts but it should be a claim that could be argued. Further, it should be clear, specific and strong. Example: Green house effect and global warming should not be considered as serious issues. This thesis is just an opinion, but not a debatable argument. Hence this is not a strong thesis. On the other hand, the following thesis on the same topic provides a claim and argument. Example: Green house effect and global warming should not be considered the most significant issue of modern times because planet earth periodically undergoes cycles of cooling and warming from time immemorial and the spells of rising temperature are beyond human control since the changes are part of the natural cycle. A thesis should be concise since it is central to the whole essay and it should be defended with evidence. Moreover, it provides a quick preview of what the writer is going to say about the topic discussed and it organizes the building blocks to be used throughout the essay. The writer considers the thesis as a tool to maintain the focus on the topic and to provide the unifying thread to the argument. As for the reader, the thesis becomes a map and helps the reader to distinguish the main ideas and engages his/her attention to details. Therefore, a thesis should be debatable, apt and easily identifiable.

4 Mnemonic Devices for Elementary Students

4 Mnemonic Devices for Elementary Students Using mnemonic devices is an excellent way to help elementary students learn and retain important information. If youre not already familiar, these are memory devices that rely on language or numbers as a strategy to trick your brain into remembering facts. The mnemonic device that begins with Thirty days hath September, April, June, and November... for example, can help students remember which months have 30 days and which have 31. Types of mnemonic devices for elementary students include rhymes, acronyms, mini-stories, and associations. Looking to use mnemonic devices to enhance your students learning? Here are four mnemonic devices for elementary students: Mnemonic device #1: rhymes For some students, it can be far easier to remember lyrics than facts from a textbook. Rhymes are great mnemonics in part because theyre closely connected to songs and often include catchy wording thats easy to recall. Teaching your student common rhyming mnemonics can help them remember key facts that will be useful throughout their education. Examples of rhyming mnemonic devices include: A rhyme to help with a common spelling confusion: I before E, except after C, or when sounding like A, like in neighbor and weigh. A rhyme for remembering Alaska and Hawaiis statehood: 59 was the date when Alaska and Hawaii became new states. [RELATED: How to Enhance Your Students Experience with Literature] Mnemonic device #2: acronyms An acronym uses the letters in a specific word to form a new keywordsuch as NASA or ATM. Remembering the keyword can help your student to recall each aspect or step in a group or concept. During a test, for example, knowing that the terms theyre trying to remember begin with certain letters can help jog their memory and relieve test-day stress. Examples of acronyms that students may encounter include: The helpful way to remember colors in a spectrum in order is ROYGBIV, which stands for red, orange, yellow, green, blue, indigo, and violet. HOMES can help you remember the names of the five Great Lakes: Huron, Ontario, Michigan, Erie, and Superior. [RELATED: Keep Calm and Study OnHow to Avoid Homework Meltdowns This School Year] Mnemonic device #3: mini-stories This strategy uses a silly sentence to help students remember a concept. Each first letter in the phrase corresponds to an aspect of the concept they need to remember. Similar to acronyms, the difference between the two lies in the phrase itself. Acronyms are almost exclusively a single word or a very short word grouping. Mini-stories, in contrast, include wording that appears as a short sentence. Examples of these mini-stories include: Never Eat Sour Watermelon, which can help children remember north, east, south, and west. Roman numerals are often difficult to recall, but the phrase I Value Xylophones Like Cows Dig Milk can help students remember this key: I=1, V=5, X=10, L=50, C=100, D=500, and M=1,000. A common math mnemonic is King Henry Died Drinking Chocolate Milk, which corresponds to kilo, hecto, deca, deci, centi, and milli in the metric system. Mnemonic device #4: associations Associations rely on the connections we make between sounds, letters, and word meanings. It makes a match between words that start with the same letterfor example, students can remember that Memorial Day happens during the month of May because the two begin with the letter m. To remember the homonyms principal and principle, for instance, students can remember that a principal is your pal, but a principle is a rule. [RELATED: How Parents Can Help Students Setand AchieveAcademic Goals] While there are common mnemonic devices students can use, students can also develop their own phrases and connections based off of items that pertain to their everyday life. Encourage your student to identify aspects of their studies that they find challenging and to create associations that may help them better recall the facts. You and your student can use a keyword that needs to be remembered and make an acrostic poem out of it, or you can think of visual or verbal personal connections related to a word. For more help with mnemonics, ask your childs teacher for ones that they use in class, or any others they might be familiar withespecially in the areas that your student struggles with or that require more memorization skills.

6 Fun and Unique Ways to Learn Music Theory

6 Fun and Unique Ways to Learn Music Theory Suzy S. Staring at the Circle of Fifths and memorizing key signatures isnt the only way to learn music theory! Here, Brooklyn, NY teacher  Liz T. shares some creative ideas to revive your learning Music theory is a very important part of your musicianship, whether it be mastering ear training, harmony, or sight reading. No matter what instrument you play or what styles you enjoy, those who learn music theory grow further as musicians. A solid knowledge can help you improve your performance, technique, composition, and analysis of music! For some, learning music theory can be very dry, or perhaps even overwhelming at first. Fortunately, it doesnt have to be all about sitting down with a theory book and memorizing scales, chords, and key signatures. There are many other interesting ways you can improve your musicianship. Here are some ideas to try that incorporate both learning and having fun! 1. Learn to play other instruments If you’re a singer, then learning the piano is vital to becoming a well-rounded vocalist. And if you’re a pianist, then being able to sing comfortably will improve your piano skills, believe it or not! The more instruments you know how to play and read the music for, the easier it will be for you! You can also try learning an instrument that plays in bass clef if you play an instrument in treble clef, to work on those transposing skills! 2. Listen to new material I recommend attending many concerts of vocalists, choirs, orchestras, and big bands, to train your ear on what all the different voices and instruments sound like. The only way to really develop your musical ear, and to start working toward perfect pitch, is by listening to the different instruments. 3. Analyze your favorite songs If you’re up for the challenge, find the sheet music for one of your favorite songs, and analyze it. For example, what are the tempo markings? What key signature is it in? Are the chords major or minor? Then, I dare you to sing the song only in solfege, not the lyrics, on the correct pitches. This is going to improve your theory and musicianship immensely! Even if you think it’s time consuming, it is very good practice. As a performer, knowing the music youre singing or playing inside and out is key! 4) Find visuals If youre a visual learner like I am, consider placing music theory posters around your music room, or somewhere you can always see them. There are also clocks that represents the Circle of Fifths (like this one); every time you look at it, you will start to memorize the key signatures! 5) Incorporate movement I encourage dancing and movement when learning music theory, especially with my younger students. This can really help you gain a sense of musicality and feel the rhythm in your body. Freeze dancing, ballet, tap, zumba, and yoga are all great ways to be lyrical with your body. And by dancing regularly, your body will begin to internalize the rhythm automatically, so that when it’s time for sight reading and performing rhythms it’s going to second nature for you! 6) Try composing a song I also encourage you to try composing music on your instrument! Write your own chord progressions, melody, and rhythms without thinking too much about it, and remember that its okay to start simple and to make mistakes. Just write whatever comes to mind. Then start to analyze what you have just written, and you may be surprised with the masterpiece you have created! I highly recommend trying out these ideas as you learn music theory they are fun, creative, and much more hands-on than staring at a book! Liz T. teaches online singing, acting, and music lessons.  She is a graduate of the Berklee College of Music with a B.M in Vocal performance and currently performs/teaches all styles of music including Musical Theater, Classical, Jazz, Rock, Pop, RB, and Country.

What is a Quotient

What is a Quotient Division is one of the 4 basic and most important operations in math. In the process of division of two numbers, one number gets divided by the other number. The answer or the result we get in the division process is known as the Quotient. So quotient is the number which is produced when a certain number is divided by another number. If the given number is being divided by its factor, then in that division the remainder produced will be 0 and the answer is the quotient. Example 1: What is the quotient when the number 48 is divided by 4? Here 48 is being divided by 4, and this can also be written in the fraction form as: 48/4. Here the number placed on the top (or in the numerator) is 48, and the number placed in the bottom (or in the denominator) is 4. Using the long division process, 48 is divided by 4 and the answer is 12. Hence the quotient when 48 is divided by 4 is 12 - 48/4 = 12. Example 2: What is the quotient when the number 63 is divided by 7? Here 63 is being divided by 7, and this can also be written in the fraction form as: 63/7. Here the number placed on the top (or in the numerator) is 63, and the number placed in the bottom (or in the denominator) is 7. Using the long division process, 63 is divided by 7 and the answer is 9. Hence the quotient when 63 is divided by 7 is 9 - 63/7 = 9.

Grammar Exercise Mixed Conditionals

Grammar Exercise Mixed Conditionals I had a Spanish class this morning and my teacher worked with me on the subjunctive tense. Soas payback Ive created a lesson on mixed conditionals.Just kidding, about the payback part. Although I did realize how confusing it gets when you are trying to speak in a mixture of times, which is what we do during normal conversations. Unfortunately or fortunately we dont usually speak in a formulaic manner, so during conversation we talk about the future and the past and the present all at the same time. Here is a somewhat formulaic look at mixing our times in conditionals:Watch the video and try the exercise below: 1. If you __________ (insulted) him yesterday, he _______ __ ____ to the wedding tomorrow. 2. If she __________ (accepts) the promotion, she ____ __ ____ to Brazil in 2015. (future using will) 3. I ________ ______ (speak) fluent Spanish, if I ____ lived in Spain for 10 years. 4. He _____ _____ ____ (left), if he ____ _____ (known) you were coming. Joan Oh, man now that I got the I, II and III conditionals, the mixed conditionals appear so those conditionals have nothing to do with the other ones?Lets see 1. If you hadnt insulted him yesterday, he would go to the wedding tomorrow. 2. If she had accepted the promotion, she will go to Brazil in 2015. (future using will) 3. I would speak fluent Spanish, if I had lived in Spain for 10 years. 4. He wouldnt have left, if he had known you were coming. But the 4th one is not the III type conditional? Now Im lost. Jesús Castañé Hi. I disagree with Joan in the first and second. Here my try.1.- If you hadn`t insulted him yesterday, he would be going to the wedding tomorrow. 2.- She accepted the promotion, she will go to Brazil in 2015 3.- I would speak fluent Spanish, if I had lived in Spain for 10 years. 4.- He wouldnt have left if he had known you were coming.Thanks in advance. Joan I really have problems with mixed conditionals. I thought there were only 3 types, and now I discover there are more of them. Why dont they teach them as type iV, V VI and so on? I dont get it. MarvinOB 1. If you hadn ´t insulted him yesterday, he would be going to the wedding tomorrow. 2. If she had accepted the promotion, she would be going to Brazil in 2015. (future using will) 3. I would speak fluent Spanish, if I had lived in Spain for 10 years. 4. He wouldn ´t have left, if he had known you were coming. LOIEnglish Perfect!
