Radioactive Isotopes
these have the same atomic number but different mass numbers
this is the average mass of all the isotopes of that element
when they occur in different amounts in a sample of the element
when isotopes have unstable nuclei due to the extra neutrons
Isotopes
these have the same atomic number but different mass numbers
Relative Atomic Mass
this is the average mass of all the isotopes of that element
