Answer 1

Answer:

It has seven electrons in its outermost shell or chlorine has 7 valence electrons.

Sodium always wants to give its one valence electron to attain the stable electronic configuration of its nearest noble gas i.e. of neon. Chlorine always wants to take one more electron in its outermost shell to complete its octet by attaining the electronic configuration of its nearest inert gas
