Diameter of a proton in nanometers

A proton is a stable subatomic particle, symbol p , H , or H with a positive electric charge of +1 e (elementary charge). Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). http://www.astronoo.com/en/articles/size-of-atoms.html
