I assume you mean for each atom. If I remember correctly, the shells go 2, 8, then 18 on the third layer.
The element sulfur (S) has 16 electrons. It has 2 electrons in its first energy level, 8 electrons in its second energy level, and 6 electrons in its third energy level.
Phosphorus has five electrons in the third energy level (n=3).
The element with 2 valence electrons on the third energy level is magnesium. Magnesium has an electron configuration of 2-8-2, with 2 electrons on the outermost energy level.
The correct electron configuration for an element with 5 electrons in the third energy level is 1s2 2s2 2p6 3s2. This configuration follows the Aufbau principle, which dictates the filling order of electrons in an atom's energy levels.
Iron has 26 electrons. The third energy level can hold a maximum of 18 electrons. Therefore, there are 18 electrons on the third energy level of iron.

Boron
In a sulfur atom, the third energy level can contain a maximum of 18 electrons. The electrons are distributed among the different orbitals in the third energy level according to the rules of electron configuration.
