Question

which of the following sets of quantum numbers can be correct for an electron in 4f orbital

Answer 1

Answer:

n=4,L=0,1,2,3,4, for L=0 m is 0 for L=1 m is -1,0,+1 ,for L=2 m is -2,-1,0,+1,+2 and for L=3 m is -3,-2,-1,0,+1,+2,+3 and for L=4 m is -4,-3,-1,-1,0,+2,+2,+3,+4

S=+1/2 and -1/2

Explanation:

For every value of 'n' There are ' n-1' values of L

and for given value of L, 'M 'has values from -L to +L

Spin S is either +1/2 and -1/2 for each electron
