Bromine is the most likely to form Bromide ions(Br-) as its outer shell holds 7 electrons, is why it is in group 7. Atoms prefer stability so having 8 electrons in the outer shell is a more stable option than having just 7. The opposite can be said for K as it has 1 electron in its outershell meaning it will be more stable if that electrons is removed. These 2 principles form the basis for ionic bonding so Potassium Bromide(KBr) is K+ and Br- ions attracted to each other via electrostatic attraction. Br higher electronegativity withdrew K's outer electron to produce K+ and Br-, These ions are then subsequentialy attracted to each other.
Im guessing u just finished your GCSE's right? if ya have any other questions to ask just message me
