The element M forms a stable ionic compound MCl₂.If M were allowed to react with bromine, the resulting compound would have the formula

Question

Quizplus · Accepted Answer

Since M forms a stable ionic compound MCl₂, we can assume that its valence is at least +1. Given that it forms a compound with Cl and ₂ in the ratio of 1:1, it suggests that M has a charge of +2. Therefore, when M reacts with bromine, it will lose two electrons to form M2+, and gain one electron from bromine to form MBr₂ with a net charge of +1. Therefore, the resulting compound would have the formula MBr₂.
