A nucleus with the same atomic number but a different mass number. Or the same number of protons, different number of neutrons.

Hi there, an isotop is the same number of electrons but different number of neutrons

Jefferson Pabalay

Isotopes are atoms of the same element, meaning the same atomic number, same proton number, but different atomic mass because they do not have the same number of neutrons.
