oxygen valency is +2
Oxygen valency is +2 because oxygen belong to overall group 16 or subgroup 6A, it means that 6 electron are present in outermost shell of oxygen if outermost valence is greater than 4 then the following formula is used for finding valency 8-valence electron = 0 8-6=2 so it proves valency ...
