I assume you mean for each atom. If I remember correctly, the shells go 2, 8, then 18 on the third layer.

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.

The element sulfur is element number 16, and has 6 electrons in the 3rd orbital level : 3s2, 3p4.
5s2 5d3
What is the neutral atom that has its first two energy levels filled, has 5 electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.
There are 8 electrons in the third energy level of a calcium atom.
There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
the maxium number of electrons that the third energy level can occupy is 18
Sulfur has 16 electrons. It has two electrons in its first energy level, eight in its second energy level, and six in its third energy level, making a total of 16 electrons.
2 electrons are in magnesiums last energy level
