Drawbacks of rutherford atomic model 1) Electrons would revolve and thus undergo acceleration,during acceleration they would radiate energy 2) Electons would then lose energy and fall into the nucleus 3)If this were so, they would be unstable but as we know today atoms are quite stable.

Drawback of Rutherford atomic model: It can't explain the stability of an atom. This model could not explain the motion of electron in circular orbits. A charged particle would release energy during acceleration and eventually, it will fall into the nucleus.

Each shell has some energy and the energy level increases from 1st shell to next shells 4. When e-s jump from lower energy to high energy level they gain energy and emit energy in opposite case 5. These energy shells are labelled as K,L,M and N or 1,2,3 and 4 .
