Chlorine has 7 valence electrons.
Chlorine is in the 17th period.Elements in the 17th period have 7 electrons in the outermost energy level. So chlorine has 7 electrons in the 3rd energy level.Chlorine has 17 electrons. It's electron configuration is [Ne] 3s2 3p5. Therefore it has 7 electrons in its third (outermost) energy level.
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.
