Atomic Physics Introduction

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

Atomic Physics

• Atomic physics is a branch of physics that studies the structure and properties of atoms
• It involves the study of atomic nuclei, electrons, and their interactions

Atomic Structure

• An atom consists of a small, dense nucleus surrounded by electrons
• The nucleus is made up of protons and neutrons, with a positive charge
• Electrons are negatively charged particles orbiting the nucleus
• Electrons occupy specific energy levels or shells around the nucleus

Energy Levels and Orbitals

• Energy levels are determined by the principal quantum number (n)
• The azimuthal quantum number (l) determines the shape of an electron's orbit
• The magnetic quantum number (m) determines the orientation of an electron's orbit
• The spin quantum number (s) determines the spin of an electron

Electron Configuration Rules

• Electrons occupy the lowest available energy levels according to the Aufbau principle
• Electrons occupy degenerate orbitals in a way that maximizes spin according to Hund's rule
• No two electrons in an atom can have the same set of quantum numbers according to the Pauli exclusion principle

Atomic Interactions

• Electromagnetic interactions occur between electrons and the nucleus or between electrons
• Magnetic interactions occur between electrons and the nucleus or between electrons
• Spin-orbit coupling is the 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
