Answer3 energy levels17 protons and electrons
Four
The period tells you how many energy levels an atom has.
2
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.

There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
Four
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
Three electron shells.
