A proton is a subatomic particle that consists of three quarks.

 


Explanation

Protons are baryons. They consist of two up quarks and a down quark. These quarks are held together by gluons, the bearers of the strong nuclear force.

antiproton

The elementary charge e is the electric charge of a single proton, or equivalently, the opposite of the electric charge of a single electron.

One gram of hydrogen gas contains about 1024 protons, that is 3 000 000 000 000 000 000 000 000 quarks.

 


Additional information

The proton was discovered in 1919 by the British-New-Zealnd physicist Ernest Rutherford.
