Answer:
d. 8
Step-by-step 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.
