WebCarbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons . History [ edit] Before 1959, both the IUPAP and IUPAC used oxygen to define the mole; the chemists defining the mole as the number of atoms of oxygen which had mass 16 g, the physicists using a similar definition but with the oxygen-16 isotope only. WebMass Number = # of Protons + # of Neutrons. Mass Number = 1 + 2. Therefore, this particular atom of hydrogen will have a mass number of 3. Note that the mass number calculated in Example 2.4. 1 does not match the number underneath the elemental symbol and name for hydrogen on the periodic table.
