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.

Br has 7 valence e-.
An electron configuration is the arrangement of the electrons around the nucleus of the atom. The electrons surround the nucleus in rings. Each ring can hold up to a certain a…mount only. The first ring can only hold up to 2 electrons. The second ring holds up to 8 electrons. The third ring can hold up to 8 electrons. And the fourth can hold up to 18 electrons. It gets alot more complicated after that with different types of bonding. For example, calcium's electronic configuration is 2,8,8,2. This means that it has two electron in the first ring, 8 in the second, 8 in the third and 2 in the fourth. The last number in the configuration tells you the group no it is placed in in the periodic table. Hope this helped!! :)
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
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1
Electronic configuration is the arrangement of electrons in the energy levels of an atom.
Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet. Br- will have 35 protons and 36 electrons. The negat…ive charge indicates it gained an electron.
The ways electrons are arranged around the nuclei of atoms in various obitals are called electron configurations. See the Related Questions links for more informat…ion
The electron configuration for an element is the arrangement of electrons in the orbits (or shells) of a neutral atom. Shells closer to the nucleus have higher binding energy.… For example, there are eleven electrons in a sodium atom (atomic number 11). Scientists have measured the quantities of energy needed to remove these electrons one by one from a sodium atom. It is quite easy to remove the the first electron. The next 8 are difficult to remove. Finally, it becomes really hard to remove the last two electrons, which are held very powerully because they are the closest to the nucleus. This is just a common representation of electron configuration. --- Example : For an atom of oxygen, there are 8 protons and 8 electrons. The first 2 electrons are in the subshell designated 1s, which can contain 2 electrons. The next 2 are in the shell designated 2s, which can also contain 2 electrons. The final 4 are in the 2p shell, which can contain up to 6 electrons. So the configuration is written as : 1s2 2s2 2p4
If it is not an ion, then this configuration is for Na 1s22s22p63s1
if you mean electron shell configuration it's 2-8-18-18-7
Bromine has five 4p electrons.
Electronic configuration refers to the number of electrons in each electron shell. There can be up to 2 electrons in the first shell, 8 in the second and third and then 18… in the fourth. You can work out the electronic configuration by looking at the periodic table: by looking at the rows you know how many shells there are and by looking at the columns you know the number of valance electrons (number of electrons in the outer shell).
The bromide ion is isoelectronic with the noble gas krypton. Thus, it has no unpaired electrons.
The electron configuration for the Bromide anion Br- is as follows: 2s1 2s2 2p6 3s2 3p6 4s2 3d10 4p5.
