In the Bohr model an electron moves in a circular orbit around the proton. Considering the orbiting electron to be a circular current loop, the magnetic moment of the hydrogen atom, when the electron is in excited state, is :
Options
- A
- B
- C
- D
Correct answer
C.
Step-by-step solution
Magnetic moment of the hydrogen atom, when the electron is in excited state, i.e.,
As magnetic moment \mathrm{I}\mathrm{A}=\mathrm{i}$\mathrm{n}^{\text{th }}M_{n^{\prime}}=\left(\frac{e}{2 m}\right) \frac{n h}{2 \pi}$
