An electron in an atom can be completely designated with the help of four quantum numbers. Out of these, the first three i.e., principal (n), azimuthal (l) and magnetic (m) quantum number are obtained from the solution of Shrodinger wave equation while the spin(s) quantum number arises from the spin of the electron around its axis clockwise or antiaclockwise. Ot of these principal quantum number tells about the size, azimuthal quantum number about the shape and magnetic quantum signifies the orientation of the electron orbital. The maximum number of electrons in a subshell having the same value of spin quantum number is given by

In any subshell, the maimum number of electrons having same value of spin quantum number is :

The maxium number of electrons in an orbital having same spin quantum number will be:

The maximum number of electrons in a shell is given by expression

Maximum number of electrons in a sub-shell with l = 3 and n = 4 is.

The maximum number of electrons that can be filled in the shell with the principal quantum number n = 4 is

Number of two electron can have the same values of … quantum numbers

Assertion : The maximum number of electrons in the shell with principle quantum number n is equal to 2n^(2) . Reason : Two electrons can have the same value of three quantum numbers n, l and m_(l) , but must have the opposite spin quantum number.
