Definition

An antiproton is the antimatter counterpart of a proton ⚛️. Protons are positively charged subatomic particles found in the nucleus of atoms. Antiprotons have the same mass as protons but a negative charge. It is stable, but quickly annihilates if it comes into contact with matter. These are produced in particle accelerators. Studying antiprotons help scientists understand the fundamental properties of matter and antimatter.

Etymology

The prefix "anti-" comes from Greek, meaning "opposite" or "against." "Proton" comes from the Greek word "protos," meaning "first." Protons were initially thought to be the fundamental building blocks of matter. Thus, "antiproton" means "opposite first particle." The term marked a significant discovery in the realm of antimatter.
