http://en.wikipedia.org/wiki/Proton#Hydrogen_ion
In chemistry, the term proton refers to the hydrogen ion, H+. Since the atomic number of hydrogen is 1, a hydrogen ion has no electrons and corresponds to a bare nucleus, consisting of a proton (and 0 neutrons for the most abundant isotope protium 1 1H). The proton is a "bare charge" with only about 1/64,000th of the radius of a hydrogen atom, and so is extremely reactive chemically. The free proton thus has an extremely short lifetime in chemical systems such as liquids and it reacts immediately with the electron cloud of any available molecule.
