Another atom question

    This is very interesting to me. Does every element differentiates solely by it's atomic number?

    Yes each element has its own unique proton number. Elements can have different isotopes which have a differing number of neutrons, but the same number as protons as the element. Deuterium and Tritium are two isotopes of Hydrogen for example.
