How to Write Chemical Formulas for Molecular Compounds. Formula writing for molecular compounds is probably the easiest type of formula writing. The key is memorizing the prefixes. Many of the prefixes you'll be familiar with since they are part of words we frequently use.

How To Write Chemical Formulas For Molecular Compounds

The rule for constructing formulas for ionic compounds containing polyatomic ions is the same as for formulas containing monatomic (single-atom) ions: the positive and negative charges must balance. If more than one of a particular polyatomic ion is needed to balance the charge, the entire formula for the polyatomic ion must be enclosed in parentheses, and the numerical subscript is placed.

How To Write Chemical Formulas For Molecular Compounds

The bonding characteristics of inorganic molecular compounds are different from ionic compounds, and they are named using a different system as well. The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas.

How To Write Chemical Formulas For Molecular Compounds

Writing the chemical formula of compounds requires identifying chemical symbols, understanding numbers in formulas and recognizing key prefixes and suffixes. Prefixes like bi- and tri- help identify the number of ions in a molecule. Compounds such as stannous fluoride use non-standard terminology.

Molecular and Empirical Formulas. 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.
