The magnetic moment `(mu)` of a revolving electron around the nucleus varies with principle quantum number `n` as

Options

A. `mu prop n^(2)`
B. `mu prop 1//n`
C. `mu prop 1//n^(2)`
D. `mu prop n`

Answer

D

Explanation

From Bothr's model of atom, electrons can resolve only in those orbits in which their angualr momentum is an intergal multiple of `h//2pi` where `h` is Planck's universal constant.
From Bohr's postualne
`mu = (pi h)/(2pi) implies mu prop n`
whre `n` is interger `(= 1,2,3..)` and is called principle quantum number.
