... A glance back at Table 4.1 on page 107 shows that the actual mass of a proton or a neutron is very small (1.67ñ10Ź24 g). The mass of an electron is 9.11ñ10Ź28 g, which is negligible in comparison. Given these values, the mass of even the largest atom is incredibly small. Since the 1920s, it has ...
