Mar 01, 2010He extracted it from the mineral euxenite, which contains eight other metals - Ca, Ce, Nb, Ta, Th, Ti, U and Y - and studied its chemistry. Nilson showed that the atomic weight of scandium was 44, and its oxide was Sc 2 O 3, of which he eventually made 2 g. It was his colleague at the university, Professor Per Theodor Cleve, who pointed out that this was Mendeleev's eka-boron.
