A relative atomic mass (also called atomic weight; symbol: Ar) is a measure of  heavy atoms. It is the ratio of the average mass per atom of an element from a given sample to 1/12 the mass of a carbon-12 atom.

Answer 2

Answer:

Relative atomic mass is the same as atomic weight, which is the older term. The number of protons an atom has determines what element it is. However, most elements in nature consist of atoms with different numbers of neutrons. An atom of an element with a certain number of neutrons is called an isotope.
