For example, the formula for Ferric oxide or Iron [III] oxide is Fe 2 O 3, which implies that 2 atoms of Fe and 3 atoms of O are present in an electrically-neutral molecule of the compound. To write a chemical formula, one must know the symbols and valencies of the elements / radicals. Example 1. Write the chemical formula for Calcium phosphate.
If you want to write a chemical equation, start by writing the chemical formulas of each reactant. Use the prefixes, such as mono-, di-, tri-, and tetra-, to figure out the number of atoms present for each element, and write this number as a subscript for each element. For example, dihydrogen monoxide would be more easily written as H2O.
