Answer: A magnesium atom lost 2 electrons, while two bromine atoms each gained 1 electron.

Magnesium is a metal that located in the second group of the periodic table. The element should be Mg2 + since it has 2 valence electron. That means, the magnesium tends to lose 2 electrons. Those 2 electrons would be divided equally between 2 bromine, so 1 electron for each bromine.
