Answer 2

Answer:

The answer is (b)4 in each atom.

Explanation:

atomic mass of oxygen is 8

i.e., 8 electrons.

Therefore, It consist two shells, k=2 and L=6

As we know, 2nd shell requires 8 electrons for the atom to be stable.

Therefore, L shell of the first atom containing 6 electrons, makes a covalent bond with the 2 electron in the L shell of the second atom, making the molecule stable and leaving 4 electron unshared in the last shell of both the atoms.
