Question

Quizplus · Accepted Answer

The chemical formula for the compound formed between magnesium and sodium would be MgNa₂. This is because magnesium needs to donate two electrons and sodium needs to accept one electron. Therefore, two sodium atoms are required to bond with one magnesium atom, resulting in the formula MgNa₂. Option B is the only choice that shows the correct number of atoms for each element in the compound.
