All the elements has an atomic weight; sometimes for the unstable radioactive elements is indicated only the value of the atomic mass of the most stable isotope.The term atomic weight is used for elements and the term atomic mass for isotopes (after the rules and the tradition of IUPAC).
By Atomic Mass
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
Copper (Cu) has a relative atomic mass because it is an average value that considers the different isotopes of copper and their abundance in nature. The relative atomic mass provides a more accurate representation of the average mass of an atom of copper compared to using just the mass number of the most abundant isotope.

the relative atomic mass for the element potassium is 39.0983
why is the atomic mass of technitium usually in brackets?
The relative atomic mass of an element is compared to carbon-12 because carbon-12 is used as a standard reference point for measuring atomic masses. This comparison helps scientists determine the mass of atoms of different elements in relation to each other.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
Approximately 4.01
The relative atomic mass of magnesium is approximately 24.305.
