PROBLEM \(\PageIndex{1}\) Based on their positions in the periodic table, predict which has the largest electron affinity: Mg, Ba, B, O, Te. Answer O PROBLEM \(\PageIndex{2}\) Based on their positions in the periodic table, predict which has the smallest electron affinity: Li, Cs, N, F, I. Answer Cs PROBLEM \(\PageIndex{3}\) Based on their positions in the periodic table, rank the following atoms in order of increasing electron affinity: F, Li, N, Rb. Answer Rb < Li < N < F PROBLEM \(\PageIndex{4}\) Based on their positions in the periodic table, rank the following atoms or compounds in order of increasing electron affnity: Mg, O, S, Si Answer S < Si < Mg < O PROBLEM \(\PageIndex{5}\) Based on their positions in the periodic table, rank the following atoms in order of increasing metallic character: F, Li, N, Rb. Answer F < N < Li < Rb PROBLEM \(\PageIndex{6}\) Based on their positions in the periodic table, predict which is the most metallic element: Mg, Ba, B, O, Te. Answer Ba PROBLEM \(\PageIndex{7}\) Based on their positions in the periodic table, predict which is the most nonmetallic element: Li, Cs, N, F, I.
