Etymology 1Edit

Coined in 1914 by British chemist Frederick Soddy from Ancient Greek ἴσος (ísos, equal; same) and τόπος (tópos, place), because the different isotopes of a chemical element always occupy the same position in the periodic table of elements. Compare the synonymous Icelandic word samsæta.
