2.29 Using s, p, d notations, describe the orbital with the following quantum numbers.

(a) n=1, l=0; (b) n = 3; l=1 (c) n = 4; l =2; (d) n=4; l=3.

(a) n = 1, l = 0 (Given)
The orbital is 1s.

(b) For n = 3 and l = 1
The orbital is 3p.

(c) For n = 4 and l = 2
The orbital is 4d.

(d) For n = 4 and l = 3
The orbital is 4f.
