Monatomic ion
A monatomic 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.[1] For example, calcium carbonate consists of the monatomic ion Ca2+ and the polyatomic ion CO2−

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.
Common type I cations Hydrogen H+ Lithium Li+ Sodium Na+ Potassium K+ Rubidium Rb+ Caesium Cs+ Magnesium Mg2+ Calcium Ca2+ Strontium Sr2+ Barium Ba2+ Aluminium Al3+ Silver Ag+ Zinc Zn2+
Common type II cations iron(II) Fe2+ ferrous iron(III) Fe3+ ferric copper(II) Cu2+ cupric copper(I) Cu+ cuprous lead(II)
Common anions hydride H− fluoride F− chloride Cl− bromide Br− iodide I− oxide O2− sulfide S2− nitride N3− phosphide P3−
