12. Three elements have the electron configurations which are as follows: 1s2 2s? 2p6 3s?, 1s2 2s2 2p6 3s² 3p 4s1 1s2 2s2 2p6 3s2 3p°, Given the following data, identify the three elements and match the appropriate values of ionization energy and atomic radius to each configuration. First ionization energies of the three elements (not in the same order) are 0.4189, 0.7377, and 1.5205 MJ/mol. The atomic radii (also not in the same order) are 1.60, 0.94, and 2.35 A.
