Give the ground state electron configuration for Br-

I got [Ar]4s23d104p5

Did I work it out right?

I don't want to start an argument but if it is Br- wouldn't it be one more electron than Br (maybe its a trick question?)

Br is [Ar] 4s2, 3d10, 4p5

so wouldn't Br- be: [Ar] 4s2, 3d10, 4p6 ?

Looks good to me, but you should space after each combination of #-subshell-electrons to avoid confusion.

Yes you did.
