Definition of Isotope

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons, resulting in atoms with different atomic masses. The chemical properties of isotopes of the same element remain the same, but isotopes can either be stable or radioactive. Radioactive isotopes undergo decay, releasing energy.

Types of isotopes:

• Stable isotopes – do not undergo radioactive decay.
• Radioactive isotopes – decay over time, releasing radiation (e.g., isotopes of uranium, radium, carbon-14).

Applications in science and technology:

• Dating with carbon isotopes to determine the age of archaeological finds.
• Use of radioisotopes to treat some types of cancer (radiotherapy).
• Use of isotopes in nuclear fusion processes to produce energy.

Context of usage for Isotope

• “Hydrogen isotopes, such as deuterium and tritium, have the same number of protons but a different number of neutrons.”
• “Radioisotopes are used in medical imaging to study organ functions and diagnose diseases.”
• “Uranium isotopes are used for dating the age of rocks.”
• “The decay of radioactive isotopes releases a significant amount of energy.”
