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

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

The maximum number of 3d electrons having spin quantum number s = +(1)/(2) are

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.

The maximum number of electrons that can have principal quantum number n = 3 & spin quantum number m_(s)=-(1)/(2) is :-

The maximum number of electrons that can have principal quantum number n=4 and spin quantum number m_(s)=-(1)/(2) is:
