Polyatomic with negative charge?

Metal + polyatomic name with NO IDE. (Keep same). EX: Sodium Nitrate (NaNO3)

Polyatomic with positive charge?

Polyatomic name + non-metal element WITH IDE. EX: Ammonium Chloride (NH4Cl)

Contains polyatomic cation and polyatomic anion?

Cation then anion EX: Ammonium Hydroxide (NH4OH)
