Question
Write a short note on magnetic orbital quantum number $(m_l).$

Answer
Magnetic orbital quantum number $(m_l):$
Magnetic orbital quantum number describes the relative spatial orientation of the orbitals in a given subshell.
It is denoted by $m;$ and it has values from $-l$ to $+l$ through zero, giving total values or total orientations equal to $(2l + 1).$
For s$-$subshell, $1 = 0,$ hence$, m_l = 0.$ Thus, s$-$subshell contains only one orbital.
For p$-$subshell, $l = 1,$ hence$, m_l = +1, 0, -1.$ Thus, p$-$subshell contains three orbitals having distinct orientations.
