Compare a mole of Ag-108 and a mole of Pt-195 using atoms, protons, electrons, and neutrons.
47 protons, 47 electrons, 108-47 neutrons.
Pt is done the same way.
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
