isotope

See also: Isotope

English

Etymology 1

From iso- (“equal”) +‎ -tope (“place”), because the different isotopes of a chemical element always occupy the same position in the periodic table of elements. The term was coined by Scottish doctor Margaret Todd in 1909 and first used publicly on February 27, 1913 by English chemist Frederick Soddy.

Noun

isotope (plural isotopes)

1. (physics) Any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei. As a consequence, atoms of isotopes will have the same atomic number but a different mass number.

Usage notes

Technically, isotopes are nuclides having the same atomic number but different mass number. In practice, the term isotope is often used instead of nuclide.

Derived terms

• isotope analysis
• isotope dilution
• isotope geochemistry
• isotope hydrology
• isotope map
