Bromine Electron Configuration :7 Easy Steps on How to Write

The element Bromine, abbreviated Br, is a member of group 17 in the periodic table. Let us talk more about bromine and how it is configured electronically.

Br has 35 electrons. It is a very powerful oxidizing agent because, like all other halogens, it requires one additional electron to complete its octet. 79Br and 81Br are two stable isotopes that are frequently described as radioactive isotopes.

This article goes into greater detail about the electronic configuration of bromine, including its orbital diagram, electronic configuration notation, ground state, and condensed electronic configuration.

How to write Bromine electron configuration

35 electrons make up bromine. In light of these three rules, these electrons will be filled.

Bromine electron configuration diagram

On the basis of the following diagram, the electronic configuration diagram of Br can be explained. The maximum number of electrons that can fit into these subshells, S, P, D, and F, respectively, are 2, 6, 10, and 14, and they fill up in increasing order of energy.

Bromine electron configuration notation

The electronic configuration notation of Br is represented by the notation;

Br : Ar18 4s2 3d10 4p5.

Bromine unabbreviated electron configuration

Br: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. When there is no noble gas configuration for the starting electrons, this is referred to as an unabbreviated electronic configuration.

ground state Bromine electron configuration

The ground state electronic configuration of Br will be 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5.

excited state of Bromine electron configuration

The electronic configuration will be 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 .In the excited state, Br will additionally require one electron to attain stability hence it will gain one electron to become stable.

ground state Bromine orbital diagram

The electrons present in the ground state of Br will consist of 2 electrons in the first shell (K shell), 8 electrons in the second shell (L shell), 18 electrons in the third shell (M shell), and the final 7 electrons in the fourth shell (N shell).

Conclusion

A reddish-brown liquid, bromine has a strong odor that irritates the skin, eyes, and respiratory system. It belongs to group 17 of the periodic table’s halogen family. Even a brief period of exposure to concentrated bromine has the potential to be extremely fatal.
