The ionization energies of sodium (in kJ/mol), starting withthe first and ending with the eleventh, are 495.9, 4560, 6900,9540, 13,400, 16,600, 20,120, 25,490, 28,930, 141,360, 170,000.Plot the log of ionization energy (y axis) versus the number ofionization (x axis); for example, log 495.9 is plotted versus 1(labeled I1, the first ionization energy), log4560 is plotted versus 2 (labeled I2, the second ionization energy), and so on. Label I1through I11 with the electrons in orbitals suchas 1s, 2s, 2p, and 3s. What can you deduce about electron shells from the breaks in the curve?
