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.
Feb 11, 2015. Bromine atom has 7 valence electrons. For a main group element, a valence electron is an electron that has the highest principal quantum number, n. The electron configuration of Br is 1sÂ² 2sÂ²2pâ¶ 3sÂ²3pâ¶ 4sÂ²3dÂ¹â°4pâµ. The electrons with the highest quantum number are the 4sÂ²4pâµ electrons. Thus, Br has seven valence electrons.
