Question

Give Scientific reason - Sodium(Na) element has valency one.​

Answer 1

Answer:

the answer is 1 because

Explanation:

The electronic configuration of sodium can be written as 2, 8, 1. 2, 8, 1 electrons are distributed in the shells K, L, M respectively. 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 1.

this is right answer
