An anion. For which element, I am not sure. Let someone else answer that.
Phosphate ion with a 3- charge. It is a polyatomic ion composed of one phosphorus atom bonded to four oxygen atoms.
Ammonim-NH4 There's also Hydronium - H3O
This is the ion acetate.
Polyatomic ions are named with their specific names, regardless of their overall charge. When naming an ionic compound with a polyatomic ion, the name of the cation is written first followed by the name of the anion (polyatomic ion).
The polyatomic ion in KNO3 (potassium nitrate) is NO3- , the nitrate ion. This ion is polyatomic because it contains four atoms bonded together. The nitrate ion is derived from nitric acid, HNO3.
The ion PO43- belongs to the category of polyatomic ions, specifically the phosphate ion. It is a negatively charged ion composed of one phosphorus atom and four oxygen atoms.
S^2- is not polyatomicPO4^3- is polyatomicHCl in not an ionN2 is not an ion
The PO4^3- ion is a polyatomic anion. It consists of a group of atoms with an overall negative charge.
A polyatomic ion is one that contains more than one atom. Many common anions are polyatomic, e.g. NO3-, SO42-, CO32-, PO43- Cations may be polyatomic, e.g NH4+, Hg22+
Phosphate ion with a 3- charge. It is a polyatomic ion composed of one phosphorus atom bonded to four oxygen atoms.

The correct name for the SO32- polyatomic ion is sulfite ion.
This is the ion acetate.
The polyatomic ion OCN- is called cyanate.
Polyatomic ions are named with their specific names, regardless of their overall charge. When naming an ionic compound with a polyatomic ion, the name of the cation is written first followed by the name of the anion (polyatomic ion).
The polyatomic ion name for NaClO is Sodium Hypochlorite
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
