atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
Furthermore, the mass of a copper atom is 63.57 times the mass of a hydrogen atom (which is 1.63×10−24 g) so that the mass of 1 m3 of copper, i.e. the density, is 8.56×1028×63.57×1.63×10−24=8900 kg m−3. On alloying, the density of a metal changes. This is ...

The atomic mass of copper of 63.546 can be attributed to the presence of an isotope in 69.17% abundance with a mass of 62.9296 u and of a second isotope of 30.83% abundance and 64.9278 u. Atomic masses and abundances of some isotopes are given in Table 2.1. TABLE 2.1. Isotopic data ...
What is the mass number of copper?Mass Number and Isotopes:A mass number is a total count of the number of protons and neutrons in an atom's nucleus. It will always be a whole number because you cannot have a fraction of a nucleon. Each element often has a number of naturally ...
