WebBecause the atomic number of every carbon atom is 6, carbon-12 has 6 protons and therefore 6 electrons. To find the number of neutrons, we subtract the number of protons from the mass number: 12 – 6 = 6 neutrons. The data in Table 1-1 can be used to calculate the total mass of these particles: Protons: 6 x 1.00728 amu = 6.04368 u WebThe atomic number equals the charge on the nucleus.
