Can a photon with higher energy than ionization energy stimulate atom?
Thanks for reply, but i know stimulation is moving an electron to higher energy levels not ionisation. Do You mean ionisation is a stimulation also.Yes, the extra energy will be turned into the kinetic energy of the electron. This is the photoelectric effect, and is the basis of photoelectron spectroscopy.
So you give us three energy levels and one ionization energy? I think you misunderstood one thing here, energy levels of an electron in its parent atom represent the binding energy in the corresponding particular orbital/state. To ionize an electron sitting at a particular state, an amount of energy which is at least as big as the binding energy must be given to that electron, the idea is simple: to overcome the binding energy. In other words, different levels have different ionization energies, for the latter must be equal to the former. Relating to your question, with 10 eV photon, any of those three energy levels won't be able to hold its electron from leaving the atom.Lets say energy levels are for simplicity 3,5,6 and its ionasation energy is 9 ev.
