  • 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
    An isotope is one of two or more forms of an element that have the same number of protons but different numbers of neutrons in the nucleus Because they have the same number of protons, isotopes occupy the same place on the periodic table and exhibit nearly identical chemical behavior

  • Isotope | Radiology Reference Article | Radiopaedia. org
    Therefore each isotope of an element has a different mass number (A), which is the simple summation of the number of protons and neutrons For example, the element carbon has six protons and its commonest isotope on earth has six neutrons, resulting in a mass number of 12 1
