Antiproton

Antiparticle of a proton.

anti-proton

An antiproton is the antiparticle of the proton. It possesses the same mass as a proton but opposite electric charge (-1e). Like all antiparticles, an antiproton annihilates upon contact with a proton, releasing energy in the form of photons or other particles.

The term 'antiproton' was coined to denote the antiparticle of a proton.

An antiproton is like a proton, but with an opposite electrical charge - it's the 'mirror image' of a regular proton.

Antiprotons were first observed in 1955 by Emilio Segrè and Owen Chamberlain
When an antiproton meets a proton, they annihilate each other in a burst of energy
Scientists use antiprotons to study the fundamental properties of matter

What is an antiproton? It's the antiparticle of a proton, meaning it has the same mass but opposite charge
Where are antiprotons found? They can be created in particle accelerators and are also found in cosmic rays
Are antiprotons stable? They quickly annihilate when they come into contact with regular matter, releasing energy
