Question:

Identify the larger species in each of the following pairs.

(a) K or K+

(b) S2- or Cl-

(c) Co2+ or Co3+

Strategy

For each pair, consider the shell the valence electrons are in. Electrons in higher shells cause the species to be larger. If they are in the same shell, the greater the nuclear charge, the smaller the species will be.
