WebFeb 4, 2024 · Isotopes are samples of an element with different numbers of neutrons in their atoms. The number of protons for different isotopes of an element does not change. Not all isotopes are radioactive. Stable isotopes either never decay or else decay very slowly. Radioactive isotopes undergo decay. WebAs you might expect, detecting uncharged particles is very challenging, and it was not until 1932 that James Chadwick found evidence of neutrons, uncharged, subatomic particles with a mass approximately the same as that of protons. The existence of the neutron also explained isotopes: They differ in mass because they have different numbers of ...
