## Atomic physics

Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around the nucleus and the processes by which these arrangements change.

## Photon mass

Photons are usually said to be massless. The mass of the photon is derived from the formula E = mc² using both the formulas Quantum Energy and the Einstein Equation, we obtain hv = mc².
