Argon has a total of 18 electrons. There are 2, 8 and 8 electrons in the 1st, 2nd and 3rd energy levels respectively.
There are eight of them.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Three (3) electrons in this energy level.
Which energy level? There are several. With different numbers of electrons...
Argon is a noble gas and being as its highest energy level is completely filled there are no electrons available for bonding in argon.

Three (3) electrons in this energy level.
Argon has 18 electrons.
Argon is a noble gas. It has a full valence shell and thus, 8 electrons.
2 electrons are in magnesiums last energy level
Two electrons can be housed in the first energy level.
In the 3rd energy level, there can be a maximum of 4 electrons.
