An electron in chromium moves from the n = 2 state to the n = 1 state without emitting a photon. Instead, the excess energy is transferred to an outer electron (one in the n = 4 state), which is then ejected by the atom. In this Auger (pronounced “ohjay”) process, the ejected electron is referred to as an Auger electron. (a) Find the change in energy associated with the transition from n = 2 into the vacant n = 1 state using Bohr theory. Assume only one electron in the K shell is shielding part of the nuclear charge. (b) Find the energy needed to ionize an n = 4 electron, assuming 22 electrons shield the nucleus. (c) Find the kinetic energy of the ejected (Auger) electron. (All answers should be in electron volts.)
