Using s, p, d notations, describes 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.


‘n’ refers to the principle quantum number

‘l’ refers to the azimuthal quantum number


‘m’ refers to the magnetic quantum number


[a] when n = 1, L = 0 [Given] The orbital is 1s. [Can have maximum of 2 electrons]


[b] For n = 3 and L = 1 the orbital is 3p. [Can have maximum of 6 electrons].


[c] For n = 4 and L = 2 the orbital is 4d. [Can have maximum of 10 electrons]


[d] For n = 4 and L = 3, the orbital is 4f. [Can have maximum of 14 electrons]
