Question

Four hypothetical salts contain ions with the same electronic configurations within each sign family. Cations A⁺ and B⁺ have radii 70 and 120 pm; anions X⁻ and Y⁻ have radii 150 and 210 pm. Which salt is expected to have the greatest covalent character by Fajans' size argument?

TestHub · Accepted Answer

A⁺ is the smaller, more strongly polarizing cation. Y⁻ is the larger, more polarizable anion. AY combines both factors that favour covalent character.
