How many electrons are there in the valence shell of the oxygen atom of water? O a. 2 O 6.4 OC. 6 O d. 8

d. 8

Explanation:

Valence electrons of oxygen = 6

Valence electrons of hydrogen = 1

The total number of the valence electrons = 6 + 2 (1) = 8

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete.

In the water molecule,

Oxygen has 2 bond pairs and two lone pairs which means that the total electrons in the valence shell is 8.
