Definitions:

Isotope

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number, but have the same number of protons in their atomic nuclei.

Neutrons

Subatomic particles with no electrical charge, found in the nucleus of an atom, and responsible for much of the mass of atoms.

Isotope

Atoms of the same element that have different numbers of neutrons, resulting in different masses but similar chemical properties.
