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 = 4mu_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

`(M)/(L) = (q)/(2m)`
`:. M prop L `
`L = (ng)/(2pi) rArr Lpropn`
Hence, `M prop n`
