Where Rutherford model can not explain the spectra of hydrogen atom, Bohr model can explain the spectra of hydrogen atom. Moreover, Bohr model introduces the circular fixed orbit that negativity charged electron revolves surrounding the the nucleus along with fixed orbit.
1. Electron revolves surrounding nucleus along with fixed circular orbit. These orbits are called energy state. Electron can jump from lower energy state to higher energy state and from higher energy state to lower energy state.
1. Each orbit have specific energy. The orbit far from nucleus have highest energy. Electron to stay highest energy state orbit required highest energy.
3. Energy state is defined as shel, named as K, L, M, N, O, P
4. When electron jump to lower energy state it releases energy, this amount is equal to mvr.
Limitation of Bohr Model
1. Bohr model can not explain the spectra of atom of higher atomic mass.
2. No explanation of sub Shel.
3. It does not comply with Heigenburg uncertainty principle.
4. It can not explain Zeeman effect, which is scattering of spectra into multiple spectral line( fine structure) with the effect of magnetic field.
5. It can not explain Stark effect that means scattering of spectra into multiple spectral line ( fine structure) with the effect of electric field.
