Write a possible full set of quantum numbers for the electron gained when a bromine atom (br) becomes a bromide ion (br−). n = ℓ = mℓ = ms =

when Br atom gains one electron its atomic numberbecomes 36 Br = 35 electronic confg =[Ar]3d104s24p5 Br- = 36 =[Ar]3d104s24p6 So the electron goes into 4p that means n = 4 , l = 1, m= +1 , ms = -1/2

What are the statements?

Answer(2) electrons;
