Chem 161-2007 Exam III Hill, Petrucci et al. Chapter 8 - Electronic Configurations, Atomic Properties, and Periodic Table Trends Periodic table and periodic trends (atomic and ionic radius, ionization energy, electron affinity, etc.) 1. Rank the following species according to increasing 1st ionization energy. (Lowest first, Highest last) F, S, Ne, K, P A. K < S < P < Ne < F B. Ne < S < K < P < F C . K < S < P < F < Ne D. F < Ne < P < S < K E. K < F < P < S < Ne According to the periodic table, the atom with the lowest ionization energy is in the lower left-hand corner, and the atom with the highest ionization energy is in the upper right-hand corner. Therefore, K < P < S < F < Ne 19 K = 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 15 P = 1s 2 2s 2 2p 6 3s 2 3p 3 16 S = 1s 2 2s 2 2p 6 3s 2 3p 4 1 9 + 1+ 15+ 16+ 5+ 6+ 9 F = 1s 2 2s 2 2p 5 10 Ne = 1s 2 2s 2 2p 6 9+ 7+ 10+ 8 + According to the above schematics, the order should also be K < P < S < F < Ne. But this order is not an option. The closest option is K < S < P < F < Ne. Is this valid? Let’s look at the subshell differences of the nearest neighbors, S and P.
