Given information
Given element:-
The valance electrons present and the tendency of gain or loss of electrons in each given element are to be calculated.
Step-by-step explanation
Step 1.
In the molecular or atomic orbitals, the electrons of an atom or molecule are distributed. This distribution of electrons is called the electronic configuration of the atom or molecule. It is used to show the orbitals of an atom in its ground state.
The atomic number is the total number of protons present in an atom.
On basis of the periodic table of elements, the atomic number of bromine is .
So bromine has electrons that are distributed in their respective orbitals.
Therefore, the electronic configuration of is
Where, is the noble gas which represents the inner electrons.
