(Sc), chemical element, rare-earth metal of transition Group IIIb of the periodic table. Scandium is a silvery-white, rather soft metal. After Dmitry Ivanovich Mendeleyev predicted (1871) its existence, tentatively calling it ekaboron, Lars Fredrik Nilson discovered (1879) its oxide, scandia, in the rare-earth minerals gadolinite and euxenite, and Per Teodor Cleve (later in 1879) identified scandium with the hypothetical ekaboron.
