A proton is about 2*10^-15 meters across (2 femtometers). It weighs 1.673 *10^ -27 kilograms.Protons carry a positive electric charge. When a single proton captures an electron it makes a hydrogen atom. Therefore a proton is the same as a hydrogen nucleus. The antiproton is an antimatter particle which has the same mass as a proton but carries a negative electric charge. What do protons look like on Soccearth?
