What is the maximum number of electrons an oxygen atom can hold in its outer energy level?

Ibelieve that the max number is five that the oxygen atom can hold in its outter shell.
hope this =)

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
