Best Answer

Neutral Bromine has three complete rings of electrons. The first ring consists of 2 electrons, the second has 8, the third 18, and the fourth has a maximum capacity of 8 electrons. Bromine only has 7 electrons in it's outer ring, though, so it needs one extra electron to complete it's ring.

So to answer your question, it needs ONE more valence electron.

How many electrons can be in the valence shell?
