  • Isotope - Wikipedia
    Isotopes are distinct nuclear species (or nuclides) of the same chemical element They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei
  • 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
    Isotopes are forms of an element that have different numbers of neutrons All isotopes of an element have the same atomic number and number of protons , but they have different atomic masses from each other
  • What are Isotopes? | IAEA - International Atomic Energy Agency
    Isotopes are forms of a chemical element with specific properties 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
  • What are Isotopes? - BYJUS
    The isotopes of a chemical element are a group of atoms that have the same atomic numbers but different mass numbers This implies that all isotopes of an element have the same number of protons in their atomic nuclei and the same number of electrons in the electron cloud surrounding the nucleus
  • Isotope Definition and Examples in Chemistry - ThoughtCo
    Isotopes are samples of an element with different numbers of neutrons in their atoms The number of protons for different isotopes of an element does not change Not all isotopes are radioactive Stable isotopes either never decay or else decay very slowly Radioactive isotopes undergo decay
  • 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 Take hydrogen, for example
  • 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 For example, the hydrogen element has three isotopes:
