Solution


Q.

 

In an atom, total number of electrons having quantum numbers n=4, |m1|=1 and ms=-12 is _________ .              [2024]

Ans.

(6)           

Principal
quantum
number (n)		 Azimuthal
quantum
number (l)		 Magnetic quantum
number (m)
             4             0 0
              1 -1, 0, +1
              2 -2, -1, 0, +1, +2
              3 -3, -2, -1, 0, +1, +2, +3

 

There are total 6 orbitals with |m|=1 (three with m=-1 and other three with m=+1). Each of these six orbitals can have an electron with ms=-12
