Electronic Configuration
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).

The difference in the number of electrons between K and L and L and M shells is the same for an atom of element X (M shell is the valence shell) and the difference value is the number of valence electrons in the M shell of the other element Y.

8thWhen I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.

10thMy experience with Abhyas Academy has been very good. When I was not in Abhyas whenever teacher ask questions I could not speak it confidently but when I came in Abhyas, my speaking skills developed and now I am the first one to give the answer of teachers question.

7thMy 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.
Shivam Rana
7thWe started with lot of hope that Abhyas will help in better understnding of complex topics of highers classes. we are not disappointed with the progress our child has made after attending Abhyas. Though need to mention that we expected a lot more. On a scale of 1-10, we would give may be 7.

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.
