The Sodium atom. 1  The Na atom has an equal number of electrons and protons (11 e-and 11 p+). 2  This atom too is unstable because the outer valance shell of electrons has only one electron in it. 3  To be stable the outer shell of electrons should have eight electrons.
Sodium has 11 electrons 2 in its its first orbital (1s2) 6 in the second(2p6) and 1 in the outer orbital (2s1) But Sodium is not stable with one lone electron spinning around, so it will always give it up whenever possible, hence it will always be one electron short- giving the element a positive charge.
