1. Write the ground-state electron configuration of a tin(IV) ion. A. [Kr]4 d 3 5 s 1 5 p 6 B. [Kr]4 d 4 5 p 6 C. [Kr]4 d 5 5 s 2 5 p 3 D. [Kr]4 d 5 5 p 5 E. [Kr]4 d 10 2. From the data below, which element is likely to be a metal? Element First ionization energy, kJ mol –1 —————————————————————————— 1 1310 2 1011 3 418 4 2080 5 947 A. 2 B. 5 C. 3 D. 1 E. 4 3. What is the electron configuration of Pb? Use shorthand notation, NO SPACES, and don't try to use superscripts, e.g. 1s 1 should be put in 1s1. Answer 4 . According to effective nuclear charge arguments, the general order of increasing electron affinity should be: Group 14 < Group 15 < Group 16. The actual ordering and the explanation are: A. 15 < 14 < 16; half filled shell stability B. 16 < 14 < 15; half filled shell stability C. 14 < 16 < 15; half filled shell stability D. 14 < 16 < 15; increasing electronegativity E. 15 < 14 < 16; increasing electronegativity 5. A simple estimate of effective nuclear charge can be made by subtracting the shielding inner shell
