Isotope
An isotope is a variant of a particular chemical element, which differs in neutron number, while retaining the same number of protons.
Neutrons
Subatomic particles found in the nucleus of an atom, having no electrical charge and a mass slightly greater than that of a proton.
Element
A pure chemical substance consisting of one type of atom, distinguished by its atomic number, which is the number of protons in its nucleus.
Isotope
Atoms of the same element that have different numbers of neutrons in their nuclei, leading to different atomic masses but the same chemical behavior.
