Describe the orbitals with the following quantum numbers using $s, p, d, f$ notations:
$(a) \ n = 2, l = 1$
$(b) \ n = 4, l = 0$
$(c) \ n = 5, l = 3$
$(d) \ n = 3, l = 2$

(N/A) The orbital notation is given by $nl$,where $n$ is the principal quantum number and the letter corresponds to the azimuthal quantum number $l$ $(l=0$ $\rightarrow s, l=1$ $\rightarrow p, l=2$ $\rightarrow d, l=3$ $\rightarrow f)$.

Quantum Numbers	Orbital
$(a) \ n=2, l=1$	$2p$
$(b) \ n=4, l=0$	$4s$
$(c) \ n=5, l=3$	$5f$
$(d) \ n=3, l=2$	$3d$
