Question

Define Valency ? with the example of Silicon and Oxygen explain it. ​

Answer 1

Answer:Valency of silicon:-Atomic number of silicon is 14. The electronic configuration of the element is-K=2, L=8,m=4. According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas. Hence valency of silicon is 4.Explanation:
