Use Lewis theory to determine the chemical formula for the compound formed between Mg and Br. A)MgBr B)Mg₂Br₃ C)Mg₃Br₂ D)MgBr₂ E)Mg₂Br

Question

Quizplus · Accepted Answer

Magnesium (Mg) has two valence electrons and tends to lose them to achieve a stable electron configuration, forming Mg²⁺ ions. Bromine (Br) has seven valence electrons and tends to gain one electron to achieve a stable electron configuration, forming Br⁻ ions. Therefore, two Br⁻ ions are needed to balance the charge of one Mg²⁺ ion, resulting in the formula MgBr₂.
