In Hydrogen atom, electron is in 4p of level energy. When this
electron drops to the ground state, define the change of magnitude
of magnetic moment.

in the bhor model of the hydrogen atom the electron is assumed
to orbit the proton in a circle at an average distance of
5.3x10^-11 m. the centripetal force keeping the electron in orbit
is due to the Coulomb force law. e= 1.6x10^-19C, electron = 9.11 x
10^-31
