MCAT Physical

A comprehensive introduction to the fundamental concepts of physics as tested on the MCAT, including mechanics, thermodynamics, electricity, and more.

Advanced Topics

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.
