The K series of the discrete spectrum of tungsten contains wavelengths of 0.0185 nm, 0.0209 nm, and 0.0215 nm. The K-shell ionization energy is 69.5 keV. Determine the ionization energies of the L, M, and N shells. Step 1 Characteristic x-rays of the K series are produced when an electron in an upper energy level of a many- electron atom drops down to fill a vacancy in the K (n = 1) shell. Assuming that the given wavelengths are the three longest wavelengths in the K series of tungsten, the transitions that produce them are from the N (n 4) shell to the K shell, from the M (n = 3) shell to the K shell, and from the L (n = 2) shell to the K shell, respectively. These transitions are shown in the energy level diagram, where 1, = 0.0185 nm, = 0.0209 nm, and 13 12 EK = 0.0215 nm. If the ionization energy of the K shell is 69.5 keV, then = -69.5 keV.
