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).

Students / Parents Reviews [10]
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.

7thMy experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
