Polyatomic ions are similar to monatomic ions, in that they have positive or negative net charge (polyatomic ions do not have a net charge of zero) which is due to the gaining or loss of …

So let’s jump right in and look at the list of common polyatomic ions. Afterwards, we’ll share some cool facts about these ions, and talk about some not-so-common ones.

Jan 1, 2026 · Some of the most useful materials we work with contain polyatomic ions. A polyatomic ion is an ion composed of more than one atom. The ammonium ion consists of one …

Because these ions contain more than one atom, they are called polyatomic ions. Polyatomic ions have characteristic formulas, names, and charges that should be memorized.
