Ernest was the fourth of the 12 children his parents brought up in New Zealand, and he was blessed with both high intelligence and a talent for sports, particularly rugby football.Bromine (Br), at atomic number 35, has a greater variety of isotopes. There are two main isotopes at 79 and 81, which average out to the 79.90amu value. While it won't change the average atomic mass, scientists have made bromine isotopes with masses from 68 to 97. As you move to higher atomic numbers in the periodic table, you will probably find even more isotopes for each element.If we look at the C-14 atom one more time, we find that C-14 does not last forever.The average atomic mass for the element is actually 12.011.Since you never really know which carbon atom you are using in calculations, you should use the average mass of an atom.
