A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved. Examples are the diatomic molecule hydrogen (H 2) and the polyatomic molecule sulfur (S 8).
A binary compound is a chemical compound that contains only two  different elements. Examples of binary ionic compounds include  calcium chloride (CaCl2), sodium fluoride (Nâ¦aF), and magnesium  oxide (MgO), whilst examples of a binary covalent compounds include  water (H2O), and sulfur hexafluoride (SF6).
