Web4 feb. 2024 · The term "isotope" was introduced by the British chemist Frederick Soddy in 1913, as recommended by Margaret Todd. The word means "having the same place" from the Greek words isos "equal" (iso-) + topos "place." Isotopes occupy the same place on the periodic table even though the isotopes of an element have different atomic weights.
