", "Thank for helping me about my question. Pssssst…enter your details to find out the price. In a binary compound, the first name will be a metal ion. We use cookies to give you the best experience possible. Use “(g)” to indicate a gas, “(s)” to indicate a solid, “(l)” to indicate a liquid, and “(aq)” to indicate a substance dissolved in water. To write the equations there are a number of important naming rules that you need to know. For example, if you are writing a formula for Dinitrogen hexafluoride, you can write the number of atoms for Fluorine by checking its Greek prefix. In ionic compounds, the Greek prefixes are not used like covalent compounds. There are also some rules which can help you identify the valence charge if you keep in mind. And a symbol is used in writing an equation of a chemical compound as it refers to that particular element. All rights reserved. Type H. Then, on the Home tab, in the Font group, click Subscript. This article has 25 testimonials from our readers, earning it our reader-approved status. Thank you very much. For example AB + CD →AD + CB. Recombine ions to make new products: NiS + NH.

After I read these articles, my result for chemistry keeps improving. (SO42-). By using our site, you agree to our. The symbol determines the type of atom or the element. So this component is made with two atoms of phosphorus and five atoms of oxygen. )/04%3A_Covalent_Bonding_and_Simple_Molecular_Compounds/4.2%3A_Covalent_Compounds%3A_Formulas_and_Names, http://www.kentchemistry.com/links/naming/NameCov.htm, http://www.kentchemistry.com/links/naming/BinaryIonic.htm, http://www.kentchemistry.com/links/naming/PolyatomicIonsB.htm, http://www.kentchemistry.com/links/naming/formulawriting.htm, http://www.chemteam.info/Equations/DoubleReplacement.html, http://antoine.frostburg.edu/chem/senese/101/reactions/faq/predicting-products-nicl2-nh42s.shtml, https://sciencenotes.org/guidelines-for-balancing-chemical-equations/, केमिकल इक्वेशन लिखें (Chemical Equation likhen), consider supporting our work with a contribution to wikiHow. Like the first element, that can be called a first name of the compound, the second element can be called the last name. Diana from A Research Guide Don't know how to start your paper? Now you should be familiar enough to write chemical formulas. Sometimes the formulas for molecules have two or more atoms with ionic groups.

I have learned more. They are as below. By continuing we’ll assume you’re on board with our cookie policy. Is it necessary to write down the status of the element under it? All the elements of group 17 have a charge of 1-, All the elements of group 16 have a charge of 2-, All the elements of group 15 have a charge of 3-. For example: Dinitrogen hexafluoride. For example: Lithium Oxide. Sulfur and Oxygen.

A good way to think about a chemical reaction is the process of baking cookies. The first name is the cation (positive ion) and the second name is the anion (negative ion). As you know now that the number of atoms of each element present in a compound is determined by the charge of each element or polyatomic ion. You should also mention the state of matter for both reactants and products in parenthesis. This may seem complex and difficult initially. For example, Cocoa Butter, Chocolate Liquor, Sugar, Lecithin and a flavoring agent makes a delicious item called Chocolate. But lithium is from group 1 and hence have a +1 charge while oxygen is from group 16 and have a 2- charge.

", "Any person who can explain a difficult idea in plain, clear words is a master teacher! This article was co-authored by Meredith Juncker, PhD. Why is respiration an exothermic reaction? For example, if you are writing the name of Lithium nitride (Li3N), the first element is Lithium. ", "I have really gained a lot from this article. The lines and symbols are used to from diagrams.
