The energy of an electron in an excited ...

The energy of an electron in an excited hydrogen atom is -3.4 eV
The angular momentum of electron is

A

`1.1 xx 10^(-34)Js`

B

`1.52 xx 10^(-34)Js`

C

`2.11 xx 10^(-34)Js`

D

`2.5 xx 10^(-34)Js`

Text Solution

Verified by Experts

The correct Answer is:
C
Angular momentum `L=(nh)/(2pi)`
`L=(2 xx 6.63 xx 10^(-34) xx 7)/(2 xx 22) =2.11 xx 10^(-34)Js`
