Solution
Valency:
Valency is defined as the combining capacity. It can also be stated as the number of electrons lost or number of electrons gained to achieve nearest noble gas configuration.
- Atomic number of Oxygen = 8
- So,its electronic configuration = 2,6
- Number of valence electrons = 6
- Valency of Oxygen = 8-6 = 2.
