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.
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.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
Chlorine has 17 electrons. In the third energy level, there are 7 electrons.
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

In oxygen, the third energy level can hold a maximum of 18 electrons. However, oxygen only has 8 electrons in total, so only 2 electrons are found in the third energy level.
Argon has 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level.
