WebIsotopes are atoms with the same atomic number (i.e. protons) and have different atomic masses (i.e. number of neutrons). For example, the element Potassium (represented by the symbol K) has three isotopes: Isotope 39K, 40K, 41K (Relative abundance in nature 93.1%, 0.01%, 6.9%). The numbers 39, 40, and 41 are the mass numbers. WebChadwick was now able to explain the existence of isotopes through his discovery of the neutron. Isotopes of the same element have the same number of protons and electrons …
