The sulfate ion (SO42-) is the polyatomic ion
A polyatomic ion. For example, ammonium, chemical formula (NH4) with a 1+ electrical overall charge.
Li(N03) is the formula of lithium nitrate, Li+ ion and NO3- ion are combined in this salt (compound)
You can treat a polyatomic ion as an element when balancing equations. The following example involves the polyatomic ion NO3-. Notice that the entire polyatomic ion is placed in parentheses and given its own subscript. 2Al(s) + 3Mg(NO3)2(aq) --> 2Al(NO3)3(aq) + 3Mg(s)
The word prefix poly- means many. So with the word polyatomic you have multiple atom types. So a polyatomic ion is an ion with multiple types of atoms in it. A polyatomic ion is composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts.
A polyatomic ion is similar to a covalent compound in as much as the atoms in the polyatomic ion are covalently bound, and it is a compound, but it has a charge. Hence it is an ION.
If the compound contains a polyatomic ion, simply name the ion.
Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
Magnesium sulfate, MgSO4 is a salt containing the magnesium ion Mg2+ and the polyatomic ion, sulfate, SO42-. These ions are ionically bonded. However within the sulfate ion, sulfur is covalently bonded to oxygen.
HCO3- is the polyatomic ion with which sodium bonds. It is the bicarbonate ion.
The sulfate ion (SO42-) is the polyatomic ion
If the compound contains a polyatomic ion, simply name the ion.

polyatomic ion
The general term is fairly straightforward, if you know a little Greek: polyatomic ions.
when an atom loses or gain an electron, it form an ion. similarly, a molecule may also lose or gain an electron to form a molecular ion. example., CH4+
When a molecular compound gains or loses electrons, it becomes a polyatomic ion.
