Answer 1

Answer:chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. Two atoms of the same element bonded in a molecule do not form a chemical compound, since this would require two different elements.

molecules held together by covalent bonds

ionic compounds held together by ionic bonds

intermetallic compounds held together by metallic bonds

certain complexes held together by coordinate covalent bonds.
