- Protons are used for12:
- Producing and studying nuclear reactions. Protons from ionized hydrogen are given high velocities in particle accelerators and are commonly used as projectiles to produce and study nuclear reactions1.
- Determining the atomic number of an atom. The number of protons in an atom determines its atomic number in the Periodic Table of Elements2.
- Determining the baryon number of an element. The number of protons plus the number of neutrons in a nucleus determines an element’s “baryon number,” which is nearly equal to the atomic mass of that element2.
