All elements have varying isotopes, which are atoms that have the same number of protons but differing numbers of neutrons and, therefore, differing atomic masses. Each proton and neutron weigh approximately 1 AMU. However, mass and energy are interchangeable which must be considered when defining ...
Copper has only two stable isotopes: ^63Cu and ^65Cu, with masses of 62.929597 amu and 64.927789 amu, respectively. The atomic mass of copper is known to be 63.546 amu. What is the isotopic abundance of 63^Cu based on the...
