What is the electron configuration for Br?
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.

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 t…aking th last noble gas used which is the 3p^6(Ar) and continue from there like so: [Ar] 4s^2 3d^10 4p^5

The electron configuration for the Bromide anion Br- is as follows:2s1 2s2 2p6 3s2 3p6 4s2 3d10 4p5.
The electron configuration for Br is [Ar]3d 10 4s 2 4p 5 .
Why the atoms attempt to obtain the stable configuration of 8 electrons Like Br has 35 electrons so it needs to get 18 electrons for the third level not 8 electrons?
An atom may hold maximum 8 electrons in its outermost shell 2 in 's' orbital and 6 in 'p' orbitals, the next incoming electron enters in next energy level because next 's' orb…ital fills prior to present 'd' orbitals, 3rd energy level may have 18 electrons in maximum but if next outer shell has at least two electrons
1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 5 Or 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 5 Or [Ar] 4s 2 3d 10 4p 5
The electronic configuration of Br - ion is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6
Bromine's atomic number is 35. Therefore, it has 35 protons and 35 electrons. Filling in the first 35 electron orbitals gives us 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p …5 .
Bromine has 35 electrons and 45 neutrons. And a less abundant isotope contains 46 neutrons and has the mass number 81.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
A bromine atom has seven electrons in its outermost shell.
Options are not given in the question. But the following species will have the same electronic configuration as Br - ion: Neutral atom: Kr Cations: Rb + , Sr 2+ Anion: Se 2…-
