The relative atomic masses of many elements are not whole numbers because :
the atoms ionize during the determinations
of the existence of isotopes
they cannot be determined very accurately
of the presence of impurities

For an element- relative atomic mass is the average of the masses of its isotopes and for the-xA0-mass of isotopes-xA0-their percentage abundance is taken into account-
