A monatomic ion is an ion consisting of a single atom. If an ion contains more than one atom, even if these atoms are of the same element, it is called a polyatomic ion.For example, calcium carbonate consists of the monatomic ion Ca 2+ and the polyatomic ion CO 3 2â .A type I binary ionic compound contains a metal (cation) that forms only one type of ion. A type II ionic compound contains a metal that forms more than one type of ion, i.e., ions with different charges.or example, calcium carbonate consists of the monatomic ion Ca 2+ and the polyatomic ion CO 3 2â . A type I binary ionic compound contains a metal (cation) that forms only one type of ion.
