- Isotope - Wikipedia
An isotope nuclide is specified by the name of the element (this indicates the atomic number) followed by a hyphen and the mass number (e g helium-3, helium-4, carbon-12, carbon-14, uranium-235 and uranium-239) [8][9] When a chemical symbol is used, e g "C" for carbon, standard notation (also known as "AZE notation" as it is written AZ E
- 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
- What Is an Isotope? Definition and Examples
Isotope Definition 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
