How many energy levels are occupied in an atom of carbon?

You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
