polyatomic
Several atoms bonded
Polyatomic describes a molecule or ion composed of more than two atoms.
In chemistry, polyatomic ions like sulfate, nitrate, and ammonium behave as single units in reactions: The polyatomic ion carries a negative charge.
The term distinguishes these multi-atom structures from monatomic (single-atom) and diatomic (two-atom) species.
