Atomic Structure — Syllabus & Topics
Topics covered in Atomic Structure for JEE Advanced Chemistry.
Topics in Atomic Structure
Discovery of Subatomic Particles
- Electron discovered through cathode ray experiments by J.J. Thomson
- Cathode rays are streams of electrons traveling from cathode to anode
- Properties of cathode rays: travel in straight lines, have mass, negatively charged, deflected by electric and magnetic fields
Atomic Models
- Thomson's plum pudding model: positive charge spread uniformly with embedded electrons
- Rutherford's nuclear model based on α-particle scattering experiment
- Key observations: most α-particles pass through, few deflect, very few bounce back
Electromagnetic Radiations and Quantum Theory
- Electromagnetic radiation has wave-particle dual nature
- Wave properties: wavelength (λ), frequency (ν), velocity (c)
- Relationship: c = νλ, where c = 3 × 10⁸ m/s
Hydrogen Spectrum and Spectral Series
- Hydrogen spectrum consists of discrete lines, not continuous spectrum
- Line spectrum proves quantized energy levels in atoms
- Spectral series: Lyman (UV), Balmer (visible), Paschen (IR), Brackett (IR), Pfund (far IR)
