Question

The change in orbital angular momentum corresponding to an electron transition inside a hydrogen atom can be:

• A. $\frac{h}{4\pi }$
• B. $\frac{h}{pi}$
• C. $\frac{h}{2\pi }$
• D. $\frac{h}{8\pi }$

Answer 1

The correct option is C $\frac{h}{2\pi }$

The change in orbital angular momentum `is $\left(l\right(l+1){)}^{-\frac{1}{2}}\frac{h}{2\pi }$

So that only $\frac{h}{2\pi }$ is possible value when the value for $l$ is $0$.
