Isotopes of the same element always have the same

AMU number

Is the answer AMU number?

  • Physics -

    The AMU (Atomic mass unit) is a unit of mass. The AMU number is therefore the approximate total mass, which includes the number of neutrons, and thus can vary between isotopes.

    The A-number represents the total number of neutrons and protons. Since the number of neutrons varies between isotopes, so does the A-number.

    The Z-number is the number of protons, and does not vary between isotopes.

    Make your choice.
