Further Explanation:
Electronic configuration:
It is the distribution of electrons of an atom in the atomic orbitals. There are two states for an electron: ground as well as the excited state. The configuration of the atom in the lowest possible energy levels is called the ground-state electronic configuration.
The filling of electrons in different energy levels or orbitals is done in accordance with the following three rules.
1. Aufbau principle: It states that the electrons are filled in various orbitals in the increasing order of their energies as follows:
2. Hund’s rule: Electron pairing will not start until each orbital is singly occupied.
3. Pauli’s exclusion principle: According to this principle, all the four quantum numbers for any two electrons can never be the same. In an orbital, the spin of two electrons has to be different. If one electron has the clockwise spin, the other would have the anticlockwise spin and vice-versa.
