Write the electronic configuration of d5 on the basis of cfse theory
Answers
Electronic configuration of elements:
An atom of an element has different shells, sub-shells and orbitals and the distribution of electrons in these shells is called the electronic configuration. Electronic configuration of any orbital can also be represented by simple notation nlx, where,
n = number of main or principle shell or the principal quantum number
l = symbol of sub-shell or orbital
x = no. of electrons present in that orbital
For example: 3p2 means that the p sub-shell in the 3rd main shell contains 2 electrons.
In order to fetch full electronic configuration of an atom, these notations are written one after the other in the increasing order of the orbital’s energy. The filling of electrons in orbitals always starts from the orbital having the lowest energy with the electrons occupying the lower energy orbitals first.
Electronic configuration of few elements is given below:
Helium = 1s2
Beryllium = 1s22s1
Carbon = 1s22s22px12py1
