Study Notes
Introduction to Atomic Physics
- Branch of physics that studies the structure and properties of atoms
- Involves the study of atomic nuclei, electrons, and their interactions
Atomic Structure
- Rutherford Model: Atom consists of a small, dense nucleus surrounded by electrons
- Nucleus: Made up of protons and neutrons, with a positive charge
- Electrons: Negatively charged particles orbiting the nucleus
- Energy Levels: Electrons occupy specific energy levels or shells around the nucleus
Atomic Energy Levels
- Principal Quantum Number (n): Determines the energy level of an electron
- Azimuthal Quantum Number (l): Determines the shape of an electron's orbit
- Magnetic Quantum Number (m): Determines the orientation of an electron's orbit
- Spin Quantum Number (s): Determines the spin of an electron
Electron Configuration
- Aufbau Principle: Electrons occupy the lowest available energy levels
- Hund's Rule: Electrons occupy degenerate orbitals in a way that maximizes spin
- Pauli Exclusion Principle: No two electrons in an atom can have the same set of quantum numbers
Atomic Interactions
- Electromagnetic Interactions: Between electrons and the nucleus, or between electrons
- Magnetic Interactions: Between electrons and the nucleus, or between electrons
- Spin-Orbit Coupling: Interaction between an electron's spin and its orbital motion
Applications of Atomic Physics
- Quantum Computing: Uses atomic physics to process information
- Magnetic Resonance Imaging (MRI): Uses atomic physics to create medical images
- Nuclear Energy: Involves the controlled release of energy from atomic nuclei
