Neon's complete electron configuration is:
1s22s22p6
Therefore, normally, neon does not have any electrons in its third energy level. As you can see, neon is a noble gas with 8 electrons in its valance shell, and is therefore chemically stable and is unlikely to react.
Neon has 8 electrons in its outside shell.
8 electrons, its outer level is full.

There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
2 electrons are in magnesiums last energy level
The third energy level of an atom can hold eight electrons.
18 electrons
