    Diatomic molecules are substances composed of only two atoms, of either the same or different elements.

    1. Sodium chloride NaCl = Na and Cl (diatomic)

    2. Nitrogen Monoxide NO = N and O (diatomic)

    3. Silicon tetrachloride SiCl4 = Si and 4Cl (not diatomic)

    4. Sulphur Dioxide SO2 = S and 2O (not diatomic)
