If the electron receives sufficient energy, it becomes exited (gains energy and can be promoted from their lowest energy (ground state) to a higher energy level. An atom with such an electron is in an exited state.
Ionisation energy- Amount of energy needed to become an ion
Electrons can only exist in a certain energy level. When electrons drop from a higher level (exited state) to their ground state they emit energy. This energy is given off as…
