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.
potassium nitrite
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).
Potassium permanganate
This is a polyatomic anion. Its called nitrite
The chemical name for an ionic compound with a polyatomic cation and polyatomic anion would typically be named using the names of the individual ions. The cation would be named first followed by the anion, with the ending of the anion typically changed to "-ide," similar to naming binary ionic compounds.

Polyatomic ion in the compound Na2O2 is known as peroxide. Such polyatomic ion contains two or more atoms covalently bonded.
If the compound contains a polyatomic ion, simply name the ion.
Ma ????? you must mean, since that is the correct atom to atom charge count, Na2CO3 Sodium carbonate
Potassium permanganate
It's a Polyatomic compound its name is Iron Bromate. Learn & Enjoy
