There are 3 possible orbitals with the values: - $n=2$, $l=1$, $m_l=-1$ - $n=2$, $l=1$, $m_l=0$ - $n=2$, $l=1$, $m_l=1$
*NOTES TO REMEMBER: In an orbital designation, - the number represents the value of $n$. - the letter represents the value of $l$, according to the following rule: $l=0$, the letter used is $s$. $l=1$, the letter used is $p$. $l=2$, the letter used is $d$. $l=3$, the letter used is $f$. The subshell is $2p$. Therefore, $n=2$ and $l=1$. For $l=1$, there are 3 possible orbitals corresponding to 3 possible values of $m_l$: $m_l=[-1,0,1]$.
