Three elements have the electron configurations 1s2 2s2 2p6 3s2 3p6, 1s2 2s2 2p6 3s2, and 1s2 2s2 2p6 3s2 3p6 4s1. The first ionization energies of the three elements (not in the same order) are 0.4189, 0.7377, and 1.505 MJ/mol. The atomic radii are 1.60, 0.94, and 2.35 .Identify the three elements and match the appropriate values of ionization energy and atomic radius to each configuration.
