What is the valence of group 6a elements​

Answer»

tion:The Group 6A elements have six valence ELECTRONS in their highest-energy orbitals (ns2np4). This is only two electrons away from having a FULL octet of eight electrons, so MANY of these elements form anions having -2 charges: OXIDE, O2-; sulfide, S2-, selenide, Se2-, etc.
