Excited State

Atom with an electron in a higher energy level than it normally occupies.

An electron absorbs electromagnetic energy to be promoted from the ground state to an excited state.

Excited states tend to have short lifetimes; they lose energy either through collisions or by emitting photons to "relax" back down to their ground states.
