Atomic and Nuclear Physics

Exploring the Smallest Building Blocks

Atomic and nuclear physics study how atoms work and what happens when their nuclei change.

Key Topics

  • Structure of the Atom: Protons, neutrons, electrons.
  • Radioactivity: Alpha, beta, gamma decay.
  • Nuclear Reactions: Fission, fusion, and their energy.

Practical Sides

  • PET scans use positron emission.
  • Cancer treatments often use radiation.

MCAT Emphasis

Understand how to balance nuclear equations and the basics of radioactive decay.

Examples

  • Interpreting the results of a radioactive tracer in medicine.

  • Calculating half-life in a nuclear decay problem.

In a Nutshell

Atomic and nuclear physics explain the behavior of atoms and the power of nuclear energy.

Key Terms

Isotope
Atoms of the same element with different numbers of neutrons.
Half-life
Time required for half a radioactive sample to decay.
