Proton
The proton is a subatomic particle with an electric charge of +1 elementary charge. It is found in the nucleus of each atom but is also stable by itself and has a second identity as the hydrogen ion, 1H+. It is composed of 3 even more fundamental particles comprising two up quarks and one down quark.
