Since Helium is a noble gas meaning it is stable, and the fact that it has one shell, it has 2 shells in its inner-most shell.
Helium has 2 electrons in its last (and only) shell. All other noble gases have 8 electrons in its valence shell.
The sodium atom (Na) has 11 electrons. The electron configuration of sodium is 2-8-1. The third noble gas shell is the second energy level or shell, which can hold a maximum of 8 electrons. Therefore, the number of electrons in the third noble gas shell of sodium is 1.
Two electrons will fill a hydrogen's outer, or valence, shell.
