  • Isotope | Examples Definition | Britannica
    isotope, 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 behaviour but with different atomic masses and physical properties Every chemical element has one or more isotopes
  • 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
  • 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
  • What are Isotopes? | IAEA
    Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element Isotopes are forms of a chemical element with specific properties
  • Isotope - Variations, Abundances, Elements | Britannica
    Several different processes can cause abundances to vary, among them radioactive decay and mass fractionation (see below) This process transmutes an isotope of one element into an isotope of another; e g , potassium-40 (40 K) to argon-40 (40 Ar) or uranium-235 (235 U) to lead-207 (207 Pb)

  • 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

    Interactive periodic table showing names, electrons, and oxidation states Visualize trends, 3D orbitals, isotopes, and mix compounds Fully descriptive writeups
  • Isotopes - GeeksforGeeks
    Isotopes are atoms of the same element that have the same atomic number but different mass numbers This difference occurs because the atoms contain the same number of protons and electrons but different numbers of neutrons in their nuclei
