  1. ATOMIC PHYSICS BY-ARPAN SHARMA
  2. *STORY OF History of the Atom Timeline era Democritus 460 BC and Dalton 1803 AD Thomson Rutherford 1897 1912 Bohr 1913 Modern Quantum Cloud Model post 1930
  3. @ HISTORY OF ATOM @ MODELS OF ATOM:- a. a. b. J.J. Thomson Model Rutherford Model Niels Bohr model @ ATOMIC SPECTRUM:- b. EMISSION SPECTRA ABSORPTION SPECTRA
  4. According to Thomson's Plum Pudding Model, a substance is consists of small spheres which are having the radius of about 10-10 m in diameter, The positive charge is spread uniformly throughout the volume of sphere called pudding, The negatively charged particles Electrons called Plums are distributed as point charges in shells ,
  5. Spherical cloud of ositive Charge egatively Charged Electrons Thomson's Plum-Pudding Model
  6. Of T *OBASON Fine Spectrum Of Atom Deflection of Alpha Particle
  7. Vaccum Lead bricks Beam of a-particles Thin gold foil (10-8 thick) Small angle scattering of most Source of cc-particles ZnS screen Laree angle Backward scattering scattering of some of a very smaEl fraction (1 in 8000 or so) Detector (Microscope)
  8. Each Atom has positive charge nucleus in it's centre and electrons revovle about the nucleus in circular paths, The force of atrraction provides the petal force require to revolve the electron about nucleus,
  9. 'Consider an atom as a planetary system. • The Newton s 2nd Law force of attraction on the electron by the nucleus is: 1 2 njs where v is the tangential velocity of the electron. 4nsonw The total energy is then: 2 E=K+V- 81t80r 3K = -9ns 2 1 2 r 8TEor This is negative, so the system is bound, which is good.
  10. DRAWBACKS OF This model could not explain the stability of atom, This model could not explain the line spectrum of atom,
