According to Coulomb's law, which ionic compound A-D has the largest electrostatic potential energy (i.e., largest in magnitude)?

Question

Quizplus · Accepted Answer

Coulomb's law indicates that the electrostatic potential energy between two charged particles is directly proportional to the product of the charges and inversely proportional to the distance between them. AlCl₃ has the largest magnitude of charge difference (Al³⁺ and Cl⁻), leading to the largest electrostatic potential energy.
