PRINCIPAL OF CHEMISTRY CLASS 11 & 12

Author Name: MR VIVEK KUMAR PANDEY | Format: Paperback | Genre : Educational & Professional | Other Details

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.[1][2] In the scope of its subject, chemistry occupies an intermediate position between physics and biology.[3] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[4] For example, chemistry explains aspects of plant chemistry (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (astrophysics), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics). Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van der Waals force bonds.

MR VIVEK KUMAR PANDEY

MY NAME IS VIVEK KUMAR PANDEY . I WAS BORN IN 30 SEP 2002,I AM FROM SURAT GUJARAT INDIA.MY DREAM WAS TO BE GOOD WRITERS ,MY FAMILY SUPPORTED ME TO SUCCESSFUL AND I CAN DO IT MY SELF.How do I write? That is a question, I believe, that cannot be honestly answered by me. I may think I did a good job writing something when in reality it could be horrible. The reader is the one who decides the quality of my writing. I do not find writing to be natural to me and therefore find it to be a real challenge. My trick as a challenged writer is to do the best I can and know that I am happy with the final outcome. It may take a while to do my best and there may be quite a few problems I run into along the way. When I write I come across a few problems that always tend to slow me down. Finding the right words is the hardest part. While I write, I try to picture what words will follow the writing I have already completed. I can rarely find the words I want or make my writing sound the way I would like it to. When I first started writing my main problem was, and still is, writer's block. I've learned to overcome that by coming up with every way I can to say what is in my head and put it on paper. It may not always work how I would like it to but it allows me to state my mind to the best of my abilities. In the end it is all about getting what is in your head onto the paper. That is one of the main factors that can affect my opinion of my writing. how to i am become a writer ,there is support of my family and teachers now i am become a writer.my fav sports is cricket and i like summer season etc.in class 5th i started writing like poem and story other.you can do everything and do it 's your self."THOSE WHO TRY NEVER GIVE UP". In order for me to have a good opinion of my writing I have to like what I am writing about. If I am not interested in the topic I am writing about I will get bored of it and my disinterest will be obvious in the end result. I enjoy being able to state my opinion and write how I feel. My best work is on a topic I enjoy and includes what I think and feel about it. From past and recent experiences I have learned that I am more proud of work I have enjoyed writing and researching for. In the past I have enjoyed writing short stories and assignments on subjects that intrigue me or are on some of my personal interests. In the end I believe it my self............
