WebThe hydrogen valence electrons act like helium, element number 2. There is 1 hydrogen valence electron and H forms 1 bond. The simple logic is that 1 + 1 = 2 for hydrogen. Helium and hydrogen are exceptions to the octet rule, and some say the “duet rule” applies. H and He are stabilized with 2 electrons, not an octet. (Duet means 2). WebNoc d.
