For fluorine it is 2 s 2, 2 p 5, for chlorine 3 s 2, 3 p 5 for bromine 4 s 2, 4 p 5, and for iodine it is 5 s 2, 5 p 5. In short, all the halogens have 7 electrons at the outermost quantum level or 5 electrons in the outermost p orbitals.
Bromine (Br) has atomic number 35. it has 35 electrons, and has one electron less of that of Krypton. so the configuration of Bromine is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5. as it regains stable configuration of Krypton by just capturing one electron, its valancy is 1. and thus is very electronagative and very reactive. it can form cobalant bond with another atom of bromine to form molecular bromine (Br2) liquid.
