Chapter 7, Problem 7.185

(choose chapter or problem)

Three elements have the electron configurations 1s2 2s2 2p6 3s2 , 1s2 2s2 2p6 3s2 3p4 , and 1s2 2s2 2p6 3s2 3p6 4s2 . The first ionization energies of these elements (not in the same order) are 0.590, 0.999, and 0.738 MJ/mol. The atomic radii are 104, 160, and 197 pm. Identify the three elements, and match the appropriate values of ionization energy and atomic radius to each configuration. Complete the following table with the correct information. Electron Configuration Element Symbol First Ionization Energy (MJ/mol) Atomic Radius (pm) 1s22s22p63s2 ________ ________ ________ 1s22s22p63s23p4 ________ ________ ________ 1s22s22p63s23p64s2
