The chloride ion (Cl-) has 8 electrons on the outermost energy level.
Phosphorus, I think. Please see the link.
Helium has two electrons which completely fills the first principal quantum level.
The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.
Electrons in the outermost principal energy level are called valence electrons.
Phosphorus has five electrons in its outermost energy level (valence electrons).

Phosphorus has 5 electrons in the the third shell.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
The maximum number of electrons that can be accommodated in the principal energy level n = 4 is 32.
The corresponding element is phosphorus.
