Question

Each oxygen atom has __ electrons in its outermost shell, out of which __ are shared in the formation of the oxygen molecule.

• A. four and two respectively
• B. four and four respectively
• C. six and two respectively
• D. six and four respectively

Answer 1

The correct option is C six and two respectively

Electronic configuration of oxygen is 2,6.
Thus, the outermost shell has six electrons.
In the formation of oxygen molecule, two pairs of electrons are shared making both atoms stable attaining the octet configuration.
It is represented as O=O.
