Question

Give scientific reason:The velency of sodium is​

Answer 1

Explanation:

Valency of Sodium

The electronic configuration of sodium can be written as 2, 8, 1. ... Therefore, valence electron in sodium is 1 and it needs to lose 1 electron from the outermost orbit to attain octet. Hence, the valency of sodium is

Answer 2

Answer:
