The 2p level in fluorine has a binding energy of -12 eV. If a photoelectron spectrum of fluorine is taken with ultraviolet light with an energy of 21.2 eV, at what kinetic energy will the 2p electrons be observed?

Question

Quizplus · Accepted Answer

The kinetic energy of the photoelectron is given by the energy of the incident light minus the binding energy of the electron. Thus, KE = 21.2 eV - 12 eV = 9.2 eV.
