Compare a mole of Ag-108 and a mole of Pt-195 using atoms, protons, electrons, and neutrons.

  • chemistry -

    47 protons, 47 electrons, 108-47 neutrons.
    Pt is done the same way.

  • chemistry -

    Since they both contain one mole, you have
    6.02 x 10^
    particles of silver and 6.02 x 10^
    particles of platinum. The difference would be in
    the number of protons, neutrons, and electrons
    present because silver contains 47 protons per
    atom, 47 electrons per atom and 61 neutrons per
    atom, while platinum contains 78 protons per
    atom, 78 electrons per atom and 117 neutrons per
    atom. A mole of platinum would contain more
    protons, electrons and neutrons but the same
    number of atoms
