The bromine electron configuration is 4s23d104p5.
You have to use configuration of electrons (spdf). In this case it will only go up to d. if we use the short hand configuration then bromine is 3d10 4s2 4p5. remember d goes before everything.
The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
1s2 2s2 2p6 3s2 3p5
The element with that electron configuration is Kr, krypton.
The bromine electron configuration is 4s23d104p5.
The electronic configuration of Bromine is [Ar] 3d10 4s2 4p5.
The long hand electron configuration of manganese is: 1s22s22p63s23p64s23d5.
