Question 1

A photon with energy of 6.7eV is fired at the mercury, describe what would happen?

Answer

Photon would be absorbed and electron would jump to n=3 (the second excited state) and almost instantaneously electron will return back to the ground state whilst simultaneously emitting a photon (emission spectrum)

Question 2

An electron with 6eV is fired at the mercury, describe what would happen?

Answer

I have no idea, please help!
