Electronic Configuration
Distribution of electrons in different orbits (shells): The distribution of electrons into different orbits of an atom was suggested by Bohr and Bury. For writing the number of electrons in different levels or shells, some rules are followed. These are:
1. The maximum number of electrons present a shell is given by the formula where, n is the orbit number or energy level 1, 2, 3….Therefore, the maximum numbers of electrons in different shells are as follows:
2. The maximum number of electrons that can be accommodated in the outermost orbit is 8. This is a very important rule and is sometimes called the octet rule. According to this rule, the presence of 8 electrons in the outermost shell makes the atom very stable.3. Electrons are not accommodated in a given shell, unless the inner shells are filled (i.e. the shells are filled in a stepwise manner).

8thA marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
