Excitation

What happens to an electron if it gains more energy than need to be excited to a higher energy level. Also can this electron only be a valence electron or can it also be an electron in the inner shell which absorbs a photon? Also what if the energy of the photon absorbed is greater than the ionisation energy?

Only photons with energies exactly equal to the difference between energy levels will be absorbed; others will be ignored.

The electron can be on any energy level, including the inner shell.

The electron will have more kinetic energy.
