(a) Suppose an unknown element has an absorption
Chapter 37, Problem 37.91(choose chapter or problem)
(a) Suppose an unknown element has an absorption spectrumwith lines corresponding to 2.5, 4.7, and 5.1 eV above itsground state, and an ionization energy of 11.5 eV. Draw anenergy level diagram for this element. (b) If a 5.1-eV photon isabsorbed by an atom of this substance, in which state was theatom before absorbing the photon? What will be the energiesof the photons that can subsequently be emitted by this atom?
