Why do some elements not have relative atomic masses eg. radium?
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).
How were the elements in the periodic table arranged?
By Atomic Mass
Why is the atomic mass scale also called the relative atomic mass scale?
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.
Why Cu has a relative atomic 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.
How the relative atomic mass is related to gram?

What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
Why is technetiums relative mass usually found in brackets on the period table?
why is the atomic mass of technitium usually in brackets?
Why is the relative atomic mass of an element relative to carbon-12?
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.
What element has a relative atomic mass of 15.5?
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.
What is the relative atomic mass of Helium?
Approximately 4.01
What is relative atomic mass of magnesium?
The relative atomic mass of magnesium is approximately 24.305.
