is the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by β −, whereas those with a mass number below 64 decay by β +. 64 Cu, which has a half-life of 12.7 hours, decays both ways. [25] 62 Cu and 64 Cu have significant applications. 62 Cu is used in 62 Cu Cu-PTSM as a radioactive tracer for positron ...
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.

The molar mass of an element or compound is its relative atomic mass (atomic weight) or relative molecular mass (molecular weight or formula weight) multiplied by the molar mass constant. The mole and the atomic mass unit (dalton) were originally defined in the International System of Units (SI) in such a way that the constant was exactly 1 g ...
