Maximum number of electrons possible with n=4, m=+1 and s=+12 is/are

a
3
b
6
c
9
d
18

detailed solution

Correct option is A

When n=4, l=0,1,2,3; m value ranges from -l to +l ; n=4, l=0, m=0; n=4, l=-1, m=-1, 0,+1; n=4, l=2, m=-1,-2, 0,+1,+2; n=4,l=3, m=-3,-2,-1, 0,+1,+2,+3; Thus for n=4, m=+1 is possible when l=1,2,3; A total of six electrons are possible; Only three electrons with s=+12 are possible;
