An electron in an atom moves from a ground state to an excited state when the electron energy increases
Further Explanation
Excitation in physics is the addition of a number of discrete energies (called excitation energies) to a system — such as the nucleus of an atom, atom, or molecule — so as to produce a change, usually from the lowest energy state (ground state) to one of the higher energies (excited state).
In nuclear, atomic and molecular systems, excited states do not continue to be distributed but instead have certain discrete energy values. Thus, external energy (excitation energy) can be absorbed in discrete quantities.
Excitation energy is stored in excited atoms and the nucleus that emits light is usually seen from atoms and as gamma radiation from the nucleus because they return to the ground state. This energy can also be lost by collisions.
In the nucleus, energy is absorbed by protons and neutrons which are transferred to an excited state. Within a molecule, energy is absorbed not only by electrons, which are very enthusiastic for higher energy levels but also by whole molecules, which are highly excited for the discrete states of vibration and rotation.
