Atomic and Nuclear Physics

Introduction

Atomic and nuclear physics is a branch of physics that deals with the structure, properties, and behavior of atoms and nuclei. This field encompasses the study of atomic structure, nuclear reactions, radioactivity, and nuclear energy.

Key Concepts

1. Atomic Structure: The structure of an atom, including the arrangement of electrons, protons, and neutrons.
2. Nuclear Reactions: Processes involving changes in the nucleus of an atom, such as fusion, fission, and radioactive decay.
3. Radioactivity: The spontaneous emission of radiation from the decay of unstable atomic nuclei.
4. Nuclear Energy: The energy released from nuclear reactions, which has applications in power generation and nuclear weapons.

Key Principles

• Quantum Mechanics: The theory that describes the behavior of particles at the atomic and subatomic levels.
• Electromagnetism: The study of the interaction between electrically charged particles and the forces they exert on each other.
• Nuclear Forces: The strong and weak forces that act within the nucleus of an atom, governing nuclear interactions.
