Answer:The electronic configuration of sodium can be written as 1s2, 2s2 2p6, 3s1. electrons are distributed in the shells K, L and M respectively. Therefore, sodium has to lose one electron to achieve it's octate.
Explanation:
Sodium has 1 electron in its outermost shell. Therefore, it is easier for it to lose 1 electron instead of gaining 7 electrons. Thus, the valency of sodium is 1 not 7.
