All isotopes of an element have the same atomic number but different mass numbers. 1) a variety of an element characterizd by a specific number of neutrons in the nucleus An isotope is an atom that has the same number of protons and a different number of neutrons

The atom is still considered the same element (still contains the same number of protons) as before but will have a different mass
The change in mass may change the atom’s properties.
To distinguish between the individual isotopes of an element, it is customary to append the mass number to the end of the name Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties Every chemical element has one or more isotopes. The meaning of isotope is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties.
Atoms of an element which have the same atomic number but different mass numbers are called isotopes of that element These isotopes are variants of the same element in which the number of protons remains constant, but the neutron count varies. Isotopes are atoms of the same element that have the same number of protons (i.e., atomic number, z) but a different number of neutrons, meaning that their mass number, a, varies Isotopes of the same element have the same number of protons but different numbers of neutrons, resulting in different atomic masses
Isotopes can be stable or unstable (radioactive), and the stability of an isotope is determined by the balance of forces within its nucleus.
