[Ar] 3d¹⁰ 4s² 4p⁵Bromine/Electron configuration
The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron. The extra valence electron gives it a negative charge.
−1
A bromide is a chemical compound containing a bromide ion or ligand. This is a bromine atom with an ionic charge of −1 (Br−); for example, in caesium bromide, caesium cations (Cs+) are electrically attracted to bromide anions (Br−) to form the electrically neutral ionic compound CsBr.
