1.	What are the possible values of four enantum numbers (n, l, m, s) for an electron in 4f orbital.(a) 4, 2, 2, +½(b) 4, 3, 2, +½(c) 5, 3, 2, -½(d) 3, 3, 1, +½
Answer» Correct option is (b) 4, 3, 2, +½ For an electron is 4f orbital n = 4 and for ‘f’ orbital l = 3 Possible values for m = -3, -2, -1, 0, +1, +2, +3 and for S = +½ and -½ So out of given choices ‘b’ is the correct choice.

Answer»

Correct option is (b) 4, 3, 2, +½

For an electron is 4f orbital

n = 4 and for ‘f’ orbital l = 3

Possible values for m = -3, -2, -1, 0, +1, +2, +3

and for S = +½ and -½

So out of given choices ‘b’ is the correct choice.
