  Energy level - Wikipedia, the free encyclopedia
Energy levels are said to be degenerate, if the same energy level is obtained by more than one quantum mechanical state.
The energy of its state is mainly determined by the electrostatic interaction of the (negative) electron with the (positive) nucleus, calculatable using the principal quantum number
Fine structure arises from relativistic kinetic energy corrections, spin-orbit coupling (magnetic dipole interaction of the electron spin with the magnetic field due to the movement in the electric field of the nucleus) and the Darwin term (contact term interaction of s-shell electrons inside the nucleus).

 Degenerate energy level - Wikipedia, the free encyclopedia
The number of occupation states available at a particular energy level is called the level's degeneracy.
In quantum theory, this usually pertains to electronic configurations and the electron energy levels, where different possible occupation states for particles may be related by symmetry.
If the symmetry is broken by a perturbation, such as applying an external electric field, this can change the energies of the states, causing energy level splitting.

 Helium Energy Levels
In the helium energy level diagram, one electron is presumed to be in the ground state of a helium atom, the 1s state.
The energy required to remove the second electron is 54.4 eV, as would be expected by modeling it after the hydrogen energy levels.
Another way to view the energy is to say that the repulsion of the electrons contributes a positive potential energy which partially offsets the negative potential energy contributed by the attractive electric force of the nuclear charge.

 ATP: The Perfect Energy Currency for the Cell
Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP).
Because the amount of energy released when the phosphate bond is broken is very close to that needed by the typical biological reaction, little energy is wasted.
The energy causes an enzyme to be attached to ADP which catalyzes the addition of a third phosphorus to form ATP.

In physics, an energy level is the potential energy for a quantum mechanical state.

 Lesson 3-6 Electron Configuration
The number of sublevels that an energy level can contain is equal to the principle quantum number of that level.
Although energy levels that are higher than 4 would contain additional sublevels, these sublevels have not been named because no known atom in its ground state would have electrons that occupy them.
This makes sense because we know that the third energy level would have 3 sublevels; an s sublevel with one orbital, a p sublevel with 3 orbitals and a d sublevel with 5 orbitals.
