The following ionic formula is not valid.Which statement BEST describes what's wrong with this formula? AlCl₂ A) It does not include both a nonmetal and a metal. B) The ratio of cations to anions is not 1:1. C) The anion is written first, followed by the cation. D) This compound does not exist in nature. E) The charges do not add up to zero.

Question

Quizplus · Accepted Answer

The formula AlCl₂ is not valid because for an ionic compound to be stable, the total charge from the cations (positively charged ions) and anions (negatively charged ions) must add up to zero, which is not the case here. This formula does not represent a real or correctly balanced ionic compound.
