Slide 7 : DIFFERENT ATOMIC MODELS
Nature Of Energy/EMR : Nature Of Energy/EMR Newton Corpuslar Theory
Wave nature Of Energy
RUTHERFORD MODEL : Wave nature Of Energy
Electron as a particle RUTHERFORD MODEL
Quantization of Energy : Quantization of Energy Spectrum of EMR
Blackbody radiation
Photo electric Effect
PHOTO ELECTRIC EFFECT : PHOTO ELECTRIC EFFECT
Bohr Model : Bohr Model Quantization of Energy and Angular Momentum
Electron as a particle
Limitations of Rutherford model , taken care of.
Limitations of Bohr Model : Limitations of Bohr Model Explain spectrum of Single electron system only.
Shapes of Molecules not explained
Zeeman effect and Stark Effect not explained
Dual nature of electron : Dual nature of electron De- Broglie concept
Dual nature of electron : Dual nature of electron Davison germer Experiment
Diffraction pattern
Wave Nature of ELECTRON : Wave Nature of ELECTRON
Heisenberg principle of Uncertainty : Heisenberg principle of Uncertainty
Schrödinger Wave Eqn. : Schrödinger Wave Eqn. Electron describing stationary wave with Psi as Wave function (Amplitude of Wave).
This eqn. solved by changing its Cartesian coordinates into spherical polar coordinates.
Importance of Psi : Importance of Psi It gives shapes of Orbitals, Molecules.
Solution of Sch. Wave Eqn. for Psi involves constants called quantum numbers providing identity to electrons (Universal constituents )
