  • Isotope - Wikipedia
    From left to right, the isotopes are protium (1 H) with 0 neutrons, deuterium (2 H) with 1 neutron, and tritium (3 H) with 2 neutrons Isotopes are distinct nuclear species (or nuclides) of the same chemical element
  • 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
    Isotopes share the same chemical properties but may have different nuclear stability and physical properties Some isotopes are stable, while others are radioactive and undergo decay Scientists use isotopes in medicine, archaeology, power generation, and scientific research
  • ISOTOPE Definition Meaning | Dictionary. com
    ISOTOPE definition: any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights
  • Isotope Basics | NIDC: National Isotope Development Center
    Isotopes are atoms of the same element that have the same number of protons (i e , atomic number, "Z") but a different number of neutrons, meaning that their mass number, "A", varies

  • What is an Isotope? - ChemTalk
    What is an isotope? An isotope is an atom that has the same number of protons and a different number of neutrons The atom is still considered the same element (still contains the same number of protons) as before but will have a different mass The change in mass may change the atom’s properties
  • Isotopes: Definition, Meaning, Examples, Uses - Scienly
    Definition: Atoms of an element which have the same atomic number but different mass numbers are called isotopes of that element These isotopes are variants of the same element in which the number of protons remains constant, but the neutron count varies
  • What Is an Isotope? A Simple Definition - ScienceInsights
    Every known element, such as oxygen or gold, is defined entirely by the number of protons in its nucleus, which is known as the atomic number The identity of an element is set by its proton count, but the number of neutrons can vary, creating different versions of the element known as isotopes
  • ISOTOPE | English meaning - Cambridge Dictionary
    Add to word list physics, chemistry a form of an atom which has a different atomic mass from other forms of the same atom but the same chemical structure (Definition of isotope from the Cambridge Academic Content Dictionary © Cambridge University Press)
