WHY RUTHERFORD THOERY GOT SOMETHING WRONG.......AND BOHR PROOF IT
Answers
Draw back of Rutherford atomic model
- Couldn't explain hydrogen spectrum.
2 .Couldn't explain electronic configuration in atom.
3 .According to electromagnetism if a charged particle is accelerated then it will emit electromagnetic waves and its energy decreases the radius also decreases so the electron will follow spiral path and ultimately it will collapse into nucleus making atom unstable .Rutherford couldn't explain these phenomena.
Bohr's Atomic Model
1 Electron revolves around the nucleus in a fixed circular orbit of definite energy.
2 Electron revolves only in those orbits whose angular momentum is an integral multiple of the factor h /2π where( h is Planck's constant).
3 As long as the electron occupy an definite energy level it does not radicate out energy that means it does not lose or gain energy.
4 The energy is emitted or absorbed only when the electron jumps from one energy level to another.If energy supplied to an electron it may jumps higher energy level to the lower by the emission of energy.
This higher energy level called excited state.
Similarly in the reverse process it may absorb energy and jump from lower to higher energy level.
This amount of energy emitted or absorbed is given by the difference of the energies of the two energy levels concerned.
