Calculate Electron Numbers in Shell

In the atomic structure, the number of electrons in each shell are vary according to their position from the centrally placed nucleus, like K-shell is the first shell which have only two numbers of electrons, L-shell is the second shell from the nucleus and have eight numbers of electrons, M-shell is the third shell which have eighteen numbers of electrons, and so on. These variable capacities of atomic shells will calculate by following equation:


2(n)2

Where, n defined as the positioning number of atomic shell from the centrally placed nucleus.


By using this expression we can calculate the capacity of any shell to bear electrons. As we knew that we start from K-shell than rest others. So, let`s see some capacities of shells, and know how many electrons they can carry:

For K-shell, n=1
Number of electrons bearing capacity
= 2(1)2
=2

For L-shell, n=2
Number of electrons bearing capacity
=2(2)2
=2(4)
=8

For M-shell, n=3
Number of electrons bearing capacity
=2(3)2
=2(9)
=18

For N-shell, n=4
Number of electrons bearing capacity
=2(4)2
=2(16)
=32
