Classifying Atoms
... The identity of an atom depends only on the number of protons, not on the number of neutrons. Many elements have atoms with the same number of protons but different numbers of neutrons. Atoms of an element that have different masses are isotopes (EYE-suh-TOHPS). The mass number of any given isotope ...
