What is the only charged polyatomic ion?
Polyatomic Ion Charge = +1 Polyatomic ions with a positive 1 charge do occur, but the main one you’ll encounter and need to know is the ammonium ion. Remember, because it is a cation, when it reacts and forms a compound, it is cited first in the chemical formula.
Is carbon dioxide a polyatomic ion?
…than two atoms are termed polyatomic molecules, e.g., carbon dioxide (CO2) and water (H2O). Polymer molecules may contain many thousands of component atoms.
Is Na2SO4 a polyatomic ion?
Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 . In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na2SO4 .
What is the formula for the polyatomic ion permanganate?

Is nitrogen a polyatomic ion?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
