Using $s, p, d, f$ notations,describe the orbital with the following quantum numbers:
$(a) n=2, l=1$
$(b) n=4, l=0$
$(c) n=5, l=3$
$(d) n=3, l=2$

(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 $l$ ($l=0$ is $s$,$l=1$ is $p$,$l=2$ is $d$,$l=3$ is $f$).

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