Answer 2

electronsAnswer:

it is 2

Explanation:

valency of oxygen is 2 as it's atomic no. is 8 meaning its first shell has 2 electrons, the second shell has 6 electrobs. second shell needs 2 more electrons to complete the perfect electron structure. hence valency  is number of electrons for perfect structure - current electrons = 8-6 = 2
