could you explain how the electron configuration for the Br ion is 2-8-18-8? does it become 8 because of the -1 charge?

Yes, because of the -1 charge Br will gain an electron, making the electron configuration 2-8-18-8. It's like when you add negative numbers ( -7 + -1 = -8 ), so the amount of electrons in the valence shell becomes 8.
