Explanation:
Detailed explanation-1: -A monatomic ion (also called simple ion) is an ion consisting of exactly one atom. If an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion. For example, calcium carbonate consists of the monatomic ion Ca2+ and the polyatomic ion CO2−3.
Detailed explanation-2: -The carbonate ion consists of one carbon atom and three oxygen atoms, and carries an overall charge of 2−. The formula of the carbonate ion is CO2−3. The atoms of a polyatomic ion are tightly bonded together, and so the entire ion behaves as a single unit. The figures below show several models.
Detailed explanation-3: -Bicarbonate Ion is a polyatomic ion whose formula is HCO3-.
