Rutherford proposed the nuclear model of an atom. The positive charge and the most of the mass of an atom was densely concentrated in extremely small region. From this very small region I mean the nucleus.
The nucleus surrounded by an electronic that moves around the nucleus with a very high speed in a circular path called orbit.
Electron and nucleus are held together by electro-static force of attraction.
Rutherford suggested that electron should move around the nucleus in a well defined orbit, however when a body is moving in a orbit, it undergoes acceleration. According to Electromagnetic wave theory, charged particles when accelerated should emit electromagnetic wave radiation. Therefore, an electro in a orbit will emit radiation, the energy carried by radiation comes from electronic motion, the orbit will continue to shrink. Thus the Rutherford model cannot explain the stability of an atom.
Rutherford model says nothing about the electronic structure of an atom
Sorry, it is long... But it will help you in effective learning.

The postulates of Bohr are given below
1)The electrons can revolve around the nucleus only in certain allowed circular orbit, and in these orbits they donot radiate energy.
2)The energy is released (in the form of radiation) only when the electrons jumps from an outer to inner orbit,and this same amount of energy is required to exite the electrons from an inner to the outer stationary orbit.
3)The angular momentum of the electrons in these stationary circular orbit is given by
mvr =nh/2pi
where m=mass of electron
v=linear velocity of the electron
r=radius of the electron
h=plank constant=6.62x10^-34J-s
n=1,2,3…I.e a whole number.
