Reviewing the common polyatomic ions, and explaining common suffixes and prefixes to help remember the formulas.

Polyatomic anions, anions composed of several atoms, can take on several suffixes. For the oxyanions, or polyatomic anions containing oxygen atoms, they will take on the –ite or –ate suffix. The difference …

Polyatomic ions combine with other ions in a ratio that produces a neutral compound overall. Subscripts are used to indicate the number of ions needed to make that neutral compound.

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, …

Learn how to name monatomic ions and ionic compounds containing monatomic ions, predict charges for monatomic ions, and understand formulas.

To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge.
