Best Answer

Diatomic homonuclear molecules are hydrogen H2, oxygen O2, nitrogen N2, fluorine F2, chlorine Cl2, bromine Br2, iodine I2 and (theoretically) astatine At2. Diatomic heteronuclear molecules encompass a broader range of compounds such as carbon monoxide CO, hydrogen chloride HCl, lithium iodide LiI, cyanide CN and calcium oxide CaO.

What element forms a diatomic molecule with a triple covalent bond?

All halogen molecules (F2, Cl2, Br2, I2) are bonded with a single covalent bond, this bond is not ionic but molecular.ionic molecules (do not exist) are joined. this is because when a diatomic molecule it transforms to a ionic molecule when its joined by a single covalent bond.
