Explanation:
Detailed explanation-1: -A polyatomic ion is an ion composed of more than one atom. The ammonium ion consists of one nitrogen atom and four hydrogen atoms. Together, they comprise a single ion with a 1+ charge and a formula of NH+4. The carbonate ion consists of one carbon atom and three oxygen atoms, and carries an overall charge of 2−.
Detailed explanation-2: -Polyatomic ions are molecular ions composed of two or more atoms bonded by covalent bonds and acting as a single unit, but unlike molecules, they have a net charge on them. The examples include cations like ammonium ion (NH+4), and hydronium ion (H3O+); and anions like hydroxide ion (OH−), and cyanide ion (CN−).
