Question

When an electron of an atom returns from an excited state to the ground state, it emits energy in the form of a photon. How does the change in energy level compare to the energy of the emitted photon?

Answer 1

Dont quote me on this, I am only a 16 yr old student studying chemistry.

I know for certain that electrons cannot exist in states between energy levels. Therefore the difference in energy levels must be equal to the energy on the emitted photon. I think the formula for this is given by. ΔE=hf. Where ΔE is the difference in energy levels. F is the frequency of light emitted and h is planks constant.

h = 6.62607004 × 10-34 m2 kg / s.

Hope that helps.
