Tin has ten stable isotopes, which is the most of any element. The term nuclide refers to the nucleus of a given isotope of an element. The nucleus of a given carbon atom will be one of the three possible nuclides discussed above. While the presence of isotopes affects the mass of an atom, it does not affect its chemical reactivity.
Thomson and Francis Aston then used a mass spectrometer to show that isotopes are atoms of the same element that have different atomic masses. The Structure of the Atom The discovery of the electron in 1897 by J. J. Thomson suggested that there was an internal structure to the "indivisible" building blocks of matter known as atoms.
