**An unknown element Q has two known isotopes 60Q and 63Q**

Atomic Weights and Isotopic Abundance The atomic weight of an element is the relative atomic mass of that element. It is actually a weighted mass of the …... The atomic mass (relative isotopic mass) of an uncommon isotope can differ from the relative atomic mass, atomic weight, or standard atomic weight, by several mass units. Atomic masses expressed in unified atomic mass units (i.e. relative isotopic masses) are always close to whole-number values, but never (except in the case of carbon-12) exactly a whole number, for two reasons:
