Atom - smallest unit of all matter, that is composed of 3 sub-atomic particles called protons, electrons and neutrons; Proton - the 'heavy' positively-charged particle in the nucleus of an atom; Electron - the very 'light' negatively-charged particle that orbits the nucleus of an atom; Neutron - the 'heavy' uncharged particle in the nucleus of an atom 7) H_3 PO_3. When two nonmetallic elements form a molecular compound, several combination ratios are often possible. For example, carbon and oxygen can form the compounds CO and CO 2.Since these are different substances with different properties, they cannot both have the same name (they cannot both be called carbon oxide). Name the following chemical compounds: 1) NaBr sodium bromide. If a search fails, you may be able to find the desired compound through a formula search. Someone who doesn’t know chemistry may think that compounds should already have names, but you know differently. Steps to Naming Covalent Compounds. 6) K 3N potassium nitride. Chemical nomenclature, replete as it is with compounds with complex names, is a repository for some very peculiar and sometimes startling names. Chemical Reactions : Imaging Agent : Journal Publishers via MeSH : Metabolic Pathways : Molecular Libraries Screening Center Network : NIH Substance Repository : Physical Properties : Protein 3D Structures : Substance Vendors : Theoretical Properties : Toxicology Chemical or scientific names are used to give an accurate description of a substance's composition. This list contains the 118 elements of chemistry. 9) KUO_4. In all the Bank and Government exams, every mark counts, and even 1 mark can be the difference between success and failure. It's important to remember that common names are inaccurate and vary from one place and time to another. First, identify the elements present. Chemical elements alphabetically listed The elements of the periodic table sorted by name in an alphabetical list.. Click on any element's name for further chemical properties, environmental data or health effects.. The collection has included novel compounds with favorable physicochemical profiles. Use Name to generate the IUPAC Name for your molecular compound; Convert name to structure; enter the systematic or trivial name for structure generation The following steps take you through the process of writing the name of any chemical you’re likely to encounter in a general chemistry class: Does the formula begin with an H? Generally questions from the topic Common Names and Formulas of Important Chemical Compounds are asked in every competitive exam. (1) ammonium thiocyanate (2) ammonium cyanide (3) nitrogen hydrogen cyanide (4) nitrogen hydrogen sulfate Answer: (1) ammonium thiocyanate Explanation: In order to name a compound, we must first figure out whether it is ionic or covalent. So, here are short notes on Common Names and Formulas of Important Chemical Compounds which will be useful for upcoming SSC as well as other competitive exams as well. A chemical compound is a chemical substance that is made of two or more atoms of different elements that share a chemical bond. Names and Symbols for Elements and Compounds Learning Objective In this lesson we will learn how to write and interpret chemical formulas for elements and compounds. Learn how to easily name ionic and covalent compounds. Se - selenium. 9) Zn(NO Quiz type: Names & formulas Molar Mass (aka formula weight) Both! It contains hundreds of chemical compounds, their molecular formula, molar mass and density. Click on a compound to find the molar mass. (* x_y = subscript y) Ex: CO = carbon monoxide _____ 1) CoSi. When it comes to chemistry, especially organic chemistry, many researchers would agree that giving strange names to chemical compounds would make the subject more appealing and helps engage the students. 5) FePO 4 iron(III) phosphate. Rules for patterns. What is the chemical name of the compound NH4SCN? Chemical Compounds List - We are providing table chart for Common Names of Certain Chemical Compounds including with Chemical Name & formulas. Names and formulas of chemical compounds 1. Names and Formulas of Chemical Compounds OriginalAlphabetical acetic acid CH₃COOH aluminum carbide Al₄C₃ aluminum chloride AlCl₃ aluminum hydroxide Al(OH)₃ ammonia NH₃ ammonium carbonate (NH₄)₂CO₃ ammonium cyanide NH₄CN ammonium hydroxide NH₄OH ammonium nitrate NH₄NO₃ ammonium oxalate (NH₄)₂C₂O₄ … What's the full name of these compounds? If the compound is a binary acid (comprised of hydrogen and one other nonmetallic element): The word “hydrogen” is changed to the prefix hydro-The other nonmetallic element name is modified by adding the suffix -ic Chemical compound names and formula can be very complex. Capitalization rules for chemical compounds and abbreviations can be confusing. Therefore, to help you get these important marks we have created a Free E-book on Names and Formulas of Common Chemical Compounds.. Ionic compounds consist of cations (positive ions) and anions (negative ions). How to write chemical names for ionic compounds You can see a listing of all my videos at my website, http://www.stepbystepscience.com 3) P 2O 5 diphosphorus pentoxide. ChemSpider is a free chemical structure database providing fast access to over 34 million structures, properties and associated information. Below is a simplified guide on how to correctly write chemical names and formula in your research paper so you can get started! At the beginning of a sentence, capitalize the first syllabic portion of the compound name. On Chemspace, we have gathered 7M+ in-stock and 1.36B+ make-on-demand screening compound collection from different suppliers including Intermed, FCH group, UORSY, - to name a few. Even so, you rarely ask someone to pass the sodium chloride at the dinner table. To denote this distinct chemical property, a mixture of water with an acid is given a name derived from the compound’s name. 8) CuOH copper(I) hydroxide. (If an element does not have a prefix, assume that the subscript is “1.” Third, apply the above naming scheme. Patterns are strings containing one or more asterisk (*) characters. Compound types: Acids Ionic compounds Molecular compounds Asterisks will match zero or more unspecified characters.

In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. (Note: If the prefix of the first element would be “mono-”, it is not needed.) For example, oxides contain one or more oxygen atoms, hydrides contain one or more hydrogen atoms, and halides contain one or more halogen (Group 17) atoms. Scientific names are mostly referenced by chemists and scientists in the usual way to derive a particular chemical compound … 6) ZnCO_3.
