The electronic configuration of Bromine is [Ar] 4s2 3d10 4p5 so there are seven valence electrons, two in the 4s orbital and 5 in the 4p orbital.
I disagree with your electronic configuration for boron. It only has 5 electrons, not 6 as you first indicated. The electron configuration for boron is 1s2, 2s2, 2p1. The valence electrons are those in the second shell, 2s2, 2p1. Since the boron ion has a +3 charge, it loses all three electrons in the second shell to leave the core electrons as 1s2, which makes the Boron ion isoelectronic with the noble gas He.
