In this video, the electronic configuration and rules for electronic configuration are explained. Know how to write the number of electrons in different energy levels or shells easily from this video. Also, know Niels Bohr’s Postulates and his Atomic Model.
What is Electronic Configuration?
Niels Bohr and Bury suggested the arrangement and distribution of electrons in different shells. The electronic configuration of an atom is simply the distribution of electrons among the different orbits/shells and subshells. These orbitals were referred to as energy levels and are represented by letters K, L, M, N, O,..... and n = 1, 2, 3, … respectively. This is one of the Niels Bohr’s Postulates which in simple words is that electrons are revolving around the nucleus along a specific pathway called orbits/shells.
Generally, the electronic configuration represents the electron distribution, when an atom is at the ground state. There are certain rules to be followed for the distribution of electrons among different shells. These rules to distribute electrons are given below.
Rules of Electronic Configuration:
There are 3 rules to do electronic configuration which are:
1. Rule 1: The formula 2n^2 is used to determine the maximum number of electrons which can be accommodated in a single shell.
2. Rule 2: A maximum of 8 electrons can be accommodated in the outermost orbit.
3. Rule 3: While filling the electrons, the inner shells should be filled first in ascending order before accommodating the electrons in the outer shells.
