How are Electrons distributed in different orbits?

1.	How are Electrons distributed in different orbits?
Answer» The distribution of electrons in an orbit is obtained by 2n², where ‘n’ is number of orbit. Therefore, Number of electrons in K-shell i.e. in 1st orbit. Here n = 1 Therefore, 2n² = 2 x 1² = 2 Thus, maximum number of electrons in K-shell i.e. 1st shell = 2 Number of electrons in L-shell, i.e. in 2nd orbit Here n = 2, therefore, 2n² = 2 x 2² = 8 Thus, maximum number of electrons in L-shell = 8 Number of electrons in M-shell, i.e. in 3rd orbit Here n = 3, therefore, 2n² = 2 x 3² = 18 Thus, maximum number of electrons in M-shell = 18 Number of electrons in N-shell, i.e. in 4th shell Here n = 4, therefore, 2n² = 2 x 4² = 32 Thus, maximum number of electrons in N-shell = 32 In similar way maximum number of electrons in any shell can be calculated.

Answer»

The distribution of electrons in an orbit is obtained by 2n², where ‘n’ is number of orbit.

Therefore,

Number of electrons in K-shell i.e. in 1st orbit.

Here n = 1

Therefore,

2n² = 2 x 1² = 2

Thus, maximum number of electrons in K-shell i.e. 1st shell = 2

Number of electrons in L-shell, i.e. in 2nd orbit

Here n = 2, therefore,

2n² = 2 x 2² = 8

Thus, maximum number of electrons in L-shell = 8

Number of electrons in M-shell, i.e. in 3rd orbit

Here n = 3, therefore,

2n² = 2 x 3² = 18

Thus, maximum number of electrons in M-shell = 18

Number of electrons in N-shell, i.e. in 4th shell

Here n = 4, therefore,

2n² = 2 x 4² = 32

Thus, maximum number of electrons in N-shell = 32

In similar way maximum number of electrons in any shell can be calculated.
