Introduction. First off, decide if the compound is covalent or ionic.Remember that covalent bonding happens when all the elements in a molecule are non-metals (e.g. carbon dioxide, water, ammonia and methane) while ionic bonding happens between a metal and a non-metal (e.g. sodium chloride, magnesium oxide). If the compound is COVALENT, it’s all in the name.
To write chemical formulas, acquaint yourself with chemical symbols, most easily found on the periodic table of elements. The periodic table is a chart of all the known elements, and it often includes both the full name of each element and its symbol, such as H for hydrogen or Cl for chlorine.
A Chemical equation or formula, as described at the beginning of the article, is a symbolic way of displaying the elements and the number of atoms in an element. The symbol determines the type of atom or the element. In order to show how many atoms an element is having in a formula, we have to use the number in subscript.
Insert chemical notation (answer box with top tabs) As you enter your answer using templates and symbols, the format of your chemical notation will appear as you see in your textbook. If your answer box doesn't offer the chemistry-specific tabs shown above: See instructions for entering chemical notation in a simple answer box.Learn More
In order to write a chemical formula, it is important to know the symbol of the elements present in the compound, formula of the radicals and the valency of the elements in that compound. Following points should be kept in mind while writing a chemical formula. Most of the compounds are binary compounds i.e. they have two elements.Learn More
For a simpler method of writing chemical formula first use the arms and link method. When writing chemical formula for compounds it is important to know the combining powers or valencies of the elements. This allows you to determine the ratio the elements combine in.Learn More
A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.) Molecular formulas are also used as abbreviations for the names of compounds.Learn More
Extending this symbolism to represent both the identities and the relative quantities of substances undergoing a chemical (or physical) change involves writing and balancing a chemical equation. Consider as an example the reaction between one methane molecule (CH 4 ) and two diatomic oxygen molecules (O 2 ) to produce one carbon dioxide molecule (CO 2 ) and two water molecules (H 2 O).Learn More

Naming and Formula Writing Overview. Learning to name and write formulas for chemical compounds requires practice with immediate feedback to help you learn from mistakes. 1. Your first step is to learn how to tell what type of compound you have. This is something you need to master before naming or writing chemical formulas.Learn More
Determine the symbol for the transition metal in the chemical formula. This is usually the first symbol written in the formula, while the symbol for the anion is written second. For example, if we have the compound FeCl2, the symbol Fe stands for the transition metal and the symbol Cl stands for the anion.Learn More
At the heart of chemistry are substances — elements or compounds— which have a definite composition which is expressed by a chemical formula.In this unit you will learn how to write and interpret chemical formulas both in terms of moles and masses, and to go in the reverse direction, in which we use experimental information about the composition of a compound to work out a formula.Learn More
Writing chemical equations is an important skill that, if mastered, will allow you to make quantitative predictions about chemical reactions. So, the purpose of this article is to help you succeed in chemistry by mastering this skill.Learn More
