Question

Write a possible full set of quantum numbers for the electron gained when a bromine atom (Br) becomes a bromide ion (Br^−).

Answer 1

The answer is n = 4 , l = 1, m= +1 , ms = -1/2

Step-by-step explanation:

When br atom gains one electron its atomic number becomes

36 br = 35

electronic config. = [ar] 3d 104s 24p5 br- = 36 = [ar] 3d 104s 24p6

so the electron goes into 4p that means

n = 4 , l = 1, m= +1 , ms = -1/2
