The halogens (F, Cl, Br etc.) are one electron short of a valence shell octet, and are among the most reactive of the elements (they are colored red in this periodic table). In their chemical reactions halogen atoms achieve a valence shell octet by capturing or borrowing the eighth electron from another atom or molecule.
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.
