Isotope - Wikipedia
Isotopes are atoms with the same number of protons but different numbers of neutrons. They are different forms of a single element and have different chemical and physical properties. Learn about the notation, examples, history, and types of isotopes, as well as the parent and daughter isotopes of radioactive isotopes.

Learn what isotopes are, how they are classified, and what are their physical and chemical properties. Find out the types of isotopes, such as stable and radioactive, and the examples of isotopes of common elements like hydrogen, carbon, and tin. Explore the facts and FAQs about isotopes with videos and quizzes.
What are Isotopes? | IAEA - International Atomic Energy Agency
Atoms of an element that contain different numbers of neutrons are called isotopes. Each isotope of a given element has the same atomic number but a different mass number ( A ), which is the sum of the numbers of protons and neutrons.
3.5: Isotopes - Chemistry LibreTexts
isotope , One of two or more species of atom s of a chemical element having nuclei with the same number of protons but different numbers of neutrons. They have the same atomic number and hence nearly identical chemical behaviour but different atomic masses.
Isotopes and mass spectrometry (article) | Khan Academy
Learn how to identify and calculate the relative abundances of isotopes using mass spectrometry, a technique that ionizes and deflects ions based on their mass-to-charge ratios. Find out what is the unified atomic mass unit, the mass number, and the concept of protons, neutrons, and electrons in an atom.
Isotope Definition and Examples in Chemistry - ThoughtCo
Learn about isotopes and isobars, two types of atoms with different numbers of neutrons or protons but the same mass number. Find out how they are used in medicine, agriculture, and industry with examples and FAQs.
Isotopes (video) | Khan Academy
Isotopes are commonly used to determine the concentration of various elements or substances using the isotope dilution method, whereby known amounts of isotopically substituted compounds are mixed with the samples and the isotopic signatures of the resulting mixtures are determined with mass spectrometry.

Isotope Basics | NIDC: National Isotope Development Center
Isotopes. Atoms that have the same atomic number (number of protons), but different mass numbers (number of protons and neutrons) are called isotopes. There are naturally occurring isotopes and isotopes that are artificially produced.
Isotopes - Chemistry LibreTexts
Isotopes of an element are atoms with the same atomic number but different mass numbers; isotopes of an element, therefore, differ from each other only in the number of neutrons within the nucleus.

Isotopes are forms of a chemical element with specific properties, such as carbon-14, the radioactive form of carbon. Isotopes are used to understand and manage water, land, food, health and more. The IAEA helps countries to produce and use isotopes and their signatures for various purposes.
