Question
Suppose an unknown element has an absorption spectrum with lines corresponding to 2.5, 4.7, and 5.1 eV above
its ground state and an ionization energy of 11.5 eV. Draw
an energy level diagram for this element. (b) If a 5.1-eV
photon is absorbed by an atom of this substance, in which
state was the atom before absorbing the photon? What will
be the energies of the photons that can subsequently be
emitted by this atom?
