The question is somewhat unclear, so my answer may be off.
Energy levels in discussion of atomic structure typically refer to the structure of the electron cloud.
Around an atoms nucleus are a series of orbitals in which electrons can be stored - they require greater amounts of stored energy to contain at higher orbitals. As such, each orbital fills from the innermost ring out.
See http://en.wikipedia.org/wiki/Atomic_orbital for the discussion of atomic orbitals on wikipedia. Each orbital refers to a specific energy level.
An Atom contains electrons in various energy levels. Electrons are usually negative and we can energy levels as orbitals, orbits or shells.
the Energy level is supposed to hold the electrons. (B.T.W., electrons and protons are basically the same thing)
electrons
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third
4
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
Principal energy levels are an atom's major energy levels, ranging in value from 1 to 7. Energy sublevels are contained within principal energy levels, and their number increases as the value of the principal energy level increases.
An atom's energy levels are orbitals which can contain 2 electrons each, assuming that they are traveling in opposite directions from each other.

The energy levels of an atom hold electrons.
They are smaller in magnitude than those between lower energy levels.

My mom!
Electrons.
Yes there are

The energy of a Photon is equal to the difference in the energy level of the Atom that it came from.
