A monatomic ion is an ion consisting of a single atom. If an ion contains more than 1 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 Ca2+ and the polyatomic ion CO32-.
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.
A binary compound is a chemical compound that contains exactly two different elements. Examples of binary ionic compounds include calcium chloride (CaCl2), sodium fluoride (NaF), and magnesium oxide (MgO), whilst examples of a binary covalent compounds include water (H2O), carbon monoxide (CO), and sulfur hexafluoride (SF6).
