A sodium atom has one electron in its outermost shell. If it loses the electron from its M shell then its L shell now becomes the outermost shell and that has a stable octet. The nucleus of this atom still has 11 protons but the number of electrons has become 10, so there is a net positive charge giving us a sodium cation Na+.On the other hand chlorine has seven electrons in its outermost shell.1. How much electrons do sodium have in its outermost shell ?a. 3b. 2c. 1d. 42. How much electrons do chlorine have in its outermost shell?a. 9b. 73.
