WebAug 17, 2024 · An atomic mass unit is defined as a mass equal to one twelfth of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu. An atom of sulfur-32 has a mass of 31.972 amu. WebAug 11, 2024 · mass number: [noun] an integer that approximates the mass of an isotope and designates the number of nucleons in the nucleus. The mass number gives an estimate of the isotopic mass measured in atomic mass units (u). For C, the isotopic mass is exactly 12, since the atomic mass unit is defined as 1/12 of the mass of C. For other isotopes, the isotopic mass is usually within 0.1 u of the mass number. For example, Cl (17 protons and 18 neutrons) has a mass number of 35 and an isotopic mass of 34.96885.
