Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature. It is always a part of a compound with other elements.

Plutonium has seven electron shells.
Bromine want an electron.
Bromine is farther down the group and has more electron shells, making it an element with a lager atomic radius.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1

It needs only 1 more electron since it already has 7 valence electrons.

Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.

The bromine electron configuration is 4s23d104p5.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
The correct number of electron clouds or shells sodium has is 3.
Phosphorus in is 3rd period. So it has 3 electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
