The gyro-magnetic ratio of an electron in an H-atom, according to Bohr model, is

Options

A. independent of which orbit it is in
B. negative
C. positive
D. increases with the quantum number n.

Answer

A

Explanation

If I is the magnitude of the angualr momentum o the electron about the central nucleus (orbital angular momentum). Vectorially.
`mu_(l)=-(e)/(2m_(e))l`.
the negative sign indicates that the angular momentum of the electron is opposite in direction to the magnetic moment.
