pH can be thought of as a measure of the concentration of this particle.
This particle can hypothetically decay to a positron and neutral pion with a mean lifetime of ten to the 33rd years. It is a hadron composed of two up quarks and one down quark and is often found in plasmas and cosmic rays. pH can be thought of as a measure of the concentration of this particle. The number of these particles in a nucleus is equal to the atomic number of an element. For 10 points, name this particle that has a charge of plus one and weighs approximately one atomic mass unit.
