Baryon number

Baryon number is a property used in physics to track certain particles, mainly protons and neutrons (called baryons). Each baryon has a baryon number of +1, and their antimatter counterparts, antibaryons, have a baryon number of -1. Other particles like electrons have a baryon number of zero. The total baryon number in an isolated system remains constant, meaning it’s conserved during all known physical processes. This concept helps scientists understand how matter behaves and interacts at a fundamental level, ensuring the balance of matter and antimatter in particle reactions and the universe.
