  • Isotope | Examples Definition | Britannica
    What is an isotope? An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties Every chemical element has one or more isotopes Why do isotopes have different properties?
  • What Is an Isotope? Definition and Examples - Science Notes and Projects
    An isotope refers to a sample of atoms When the number of protons and neutrons of an individual atom is studied, it is called a nuclide of the element In nuclear science, the term nuclide is preferred over the term isotope

  • 2. 6: Isotopes - When the Number of Neutrons Varies
    The isotope of carbon known as carbon-14 is an example of a radioisotope In contrast, the carbon isotopes called carbon-12 and carbon-13 are stable This whole discussion of isotopes brings us back to Dalton's Atomic Theory According to Dalton, atoms of a given element are identical But if atoms of a given element can have different numbers
