Match the ions below with the pictures that represent their relative sizes. Justify your answers. Ions: Se2– K+ Ga3+ Br– Ca2+ Copyright Cengage Learning. Powered by Cognero. Page 19 Chapter 3 - Bonding: General Concepts ANSWER: K+ Ca2+ Ga3+ Se2– Br– Se2– and Br– each have the electron configuration of Kr. K+, Ca2+, and Ga3+ each have the electron configuration of Ar. The Se2– and Br– contain electrons in a higher energy level, therefore making their radii larger than the other three ions. Since Br– has more protons, this will draw the electrons in slightly more than Se2– (due to a slightly higher effective nuclear charge). For the other three ions, Ga3+ will be the smallest because it has the highest number of protons. K+ has the least number of protons and is thus the biggest ion of the three. POINTS: 1 74.
