Etymology: Gadolinium was named for Johan Gadolin, a chemist who was a Swedish-speaking Finn. The name honours him because the element was first identified in the mineral that now bears his name, gadolinite. Gadolin studied the dense black ore, and the element later isolated from it was given his surname with the chemical suffix "-ium", the standard ending for metallic elements. The suffix is the least surprising part of the word. Elements were named in this period after places, planets, and people, and the "-ium" ending marks the new element as a metal. Gadolin himself never isolated the element; the name reflects his work on the mineral rather than a discovery of the metal in his own hands.
