There are 7 Energy Levels of electrons called shells, and there are 4 sub-shellsnamed as sub-shells s, p, d, and f. They are ordered as 1s - 2s - 2p - 3s- 3p - 4s - 3d - 4p - 5s- 4d - 5p - 6s - 4f - 5d - 6p - 7s - 5f - 6d - 7p - 6f - 7d - 7f. "s" sub-shells consists of 2 electrons, "p" sub-shells consists of 6 electrons, "d" sub-shells consists of 10 electrons, and "f" sub-shells consists of 14 electrons. The first shell has 2 electrons, the second shell has 8 electrons, the third shell has 18 electrons, the fourth shell has 32 electrons, the fifth shell has 50 electrons, the sixth shell has 72 electrons, and the seventh and last shell has 98 electrons. Oh!!! By the way, the formation of the energy levels is like the solar system. The sun is the nucleus and the proton while the Planets are the electrons. There are seven orbits and each orbit has its own electron count. I mentioned it earlier in this answer of mine.
The energy of an electron cloud is determined by adding all the energies of the individual electrons in the cloud to get a total energy. Obtaining these numbers requires a little digging, and then some clever mathematics. It isn't going to be a walk in the park, but it can be done. We don't usually talk about the energy of an atom's electron cloud as a whole. We normally concentrate on the energy of individual electrons about the atom, particularly the valence electrons. As chemical bonding occurs, the energy of these electrons changes because of the effect of the bond.
Electrons orbit the atom's nucleus in energy levels.
Each primary energy level can be occupied by up to 2n2 electrons
n = 1, maximum number of electrons = 2
n = 2, maximum number of electrons = 8
n = 3, maximum number of electrons = 18
IN the first energy level there are 2 electrons!
hope this helped!
s, p, d, and f
those closest to the nucleus
that depends on the number of electrons the more electrons the more energy
electrons
Electrons are arranged around the atomic nucleus forming the electron clouds.
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.
Bohr did not speak of fixed LOCATIONS of electrons, he spoke of fixed energy levels. His name for such energy levels was "orbits" or "orbitals."
Electrons are located in energy levels within the electron cloud.

Sodium atoms do have electrons that are arranged in energy levels. The electron configuration of sodium is 1s22s22p63s1.
The energy levels of an atom hold electrons.
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
Energy levels from 3 and above can have more than 8 electrons maximum. Maximum of 2n2 electrons is possible where n is the energy level.
Two electrons can be housed in the first energy level.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
