Definitions:

Isotopes

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nuclear mass, yet retain their identity as that element.

Neutrons

Subatomic particles found in the nucleus of an atom, with no electric charge and a mass slightly larger than that of protons.

Protons

Positively charged subatomic particles found within the nucleus of an atom, defining the element's atomic number.

Electrons

Negatively charged particles present in all atoms, responsible for conducting electricity in solid materials.
