What is an isotope?
... What is an isotope? Number of protons for an atom of a specific element never changes. Number of neutrons can change. Two atoms with equal protons but different neutrons are called isotopes of each other. All atoms in existence are isotopes! Some isotopes are just more common than others. ...
