WebThe simplest atom is the hydrogen isotope protium, which has atomic number 1 and atomic mass number 1; it consists of one proton and one electron. The hydrogen isotope which also contains one neutron so is called deuterium or hydrogen-2; the hydrogen isotope with two neutrons is called tritium or hydrogen-3. WebFor example, the dalton (1 Da) is defined as 1/12 of the mass of a 12 C atom—but the atomic mass of a 1 H atom (which is a proton plus electron) is 1.007825 Da, so each nucleon in 12 C has lost, on average, about 0.8% of its mass in the form of binding energy.
