$\huge\pink{Answer- }$

$\blue{Electronic\: Configuration:}$

⭐The distribution of electrons of an atom in atomic orbitals is known as electronic configuration.♥

⭐ It represents how the electrons are distributed in its atom among the shells and the sub-shells.♥

⭐It also helps to predict the chemical, physical, magnetic, electric behaviour of substance.♥

⭐The order for filling orbitals is as follows: 1s 2s 2p 3p 4s 3d 4p 5s 6s 4f 5d 6p 7s 5f 6d 7p 8s.

⭐ For example: Electronic configuration of neon atom is 1s2 2s2 2p6.
