Question

Determine the minimum angular momentum of an electron with the magnetic quantum numbers as -1 , 0 , +1.

• A. $\sqrt{\frac{3}{2}\frac{h}{\pi }}$
• B. $\frac{h}{\pi }$
• C. $\frac{2h}{\pi }$
• D. $\frac{3}{2}\frac{h}{\pi }$

Answer 1

The correct option is B $\frac{h}{\pi }$

$m=-1,0,+1\Rightarrow l=1,p-orbital$
minimum p-orbital lies in $n=2$
$Angularmomentum=\frac{nh}{2\pi }=h/\pi$
