In hydrogen atom, the electron is at a d...

In hydrogen atom, the electron is at a distance of 4.768Ã… from the nucleus. The angular momentum of the electron is:

A

`(3h)/(2pi)`

B

`(h)/(2pi)`

C

`(h)/(pi)`

D

`(3h)/(pi)`

Text Solution

Verified by Experts

The correct Answer is:
A
`r=(n^(2))/(z)xx0.529`Ã…
`4.768=(n^(2))/(1)xx0.529`
`n=3`
`therefore` Angular momentum `(mvr)=(nh)/(2pi)=(3h)/(2pi)`.
