The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount in a liquid determines whether the solution is acidic or basic. Protons are also extremely mobile, moving through water by jumping from one water molecule to another.
