An orbital electron is the ground state ...

An orbital electron is the ground state of hydrogen has the magnetic moment `mu_1`. This orbital electron is excited to 3rd excited state by some energy transfer to the hydrogen atom. The new magnetic moment fo the electron is `mu_2` then

A

`mu_(1)=2 mu_(2)`

B

`2mu_(1) =mu_(2)`

C

`16mu_(1)=mu_(2)`

D

`4mu_(1)=mu_(2)`.

Text Solution

Verified by Experts

The correct Answer is:
D
`mu= niA=IA , mu =(qv)/(2pi r) xx pi r^(2)`
`M alpha v r ` where ` v alpha (z)/(n) & r alpha (n^2)/( z) , upsilon_(n) alpha =(1)/(n)`
