Br has the following electron configuration: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5, therefore Br has 7 electrons in the valence shell and has the capacity to accept 1 electron for bonding.

You can easily find out how many valance electrons an element carries by looking at the group number of the element on the periodic table.
As Bromine is in group 7, so it has 7 valence electrons.
