Ionium Thorium Derived

Tracers of modern technoscience (pdf) Paperity

British radioactivist Frederick Soddy crafted the word isotope in 1912 to account for the chemical identity of two distinct radio-elements, ionium (thorium-234) and thorium (thorium-232). Ten years later, the concept had proved its value throughout the periodic table, thanks to Francis Aston's experimental work with mass spectroscopes that were designed to reveal new elements.
