What is the electron configuration of elements Br?

Answer 1

The electron configuration of bromine (Br) is [Ar] 4s2 3d10 4p5. This configuration indicates that bromine has 35 electrons, with two electrons in the 4s orbital, ten electrons in the 3d orbital, and five electrons in the 4p orbital. The [Ar] represents the electron configuration of argon, which is the noble gas that comes before bromine in the Periodic Table and contributes 18 electrons to the overall configuration.

Answer 2

argon is because it's the last noble gas used to get to Br.. it's like a short cut, instead of writing 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^5 you can skip a lot of it by taking th last noble gas used which is the 3p^6(Ar) and continue from there like so: [Ar] 4s^2 3d^10 4p^5

Answer 3

The electron configuration of bromine (Br) is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5.

Answer 4

The electronic configuration of Br atom is [Ar] 4s2 3d10 4p5. Since, bromide ion has gained 1- charge by acquiring one more electron, its electronic configuration is [Ar] 4s2 3d10 4p6.

Answer 5

The electron configuration for Br is [Ar]3d104s24p5.

Answer 7

The electronic configuration of Br- ion is 1s22s22p63s23p64s23d104p6

Answer 8

Bromine's atomic number is 35. Therefore, it has 35 protons and 35 electrons. Filling in the first 35 electron orbitals gives us 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5.
