Scandium


Scandium was discovered in 1876 by Lars Fredrik Nilson, in Uppsala, Sweden, through the study of the euxenite ore, although its existence had already been inferred by Dimitri Mendeleev in 1868, based in its Periodic Table of the Elements. It is not a rare element, being twice more abundant than boron. However, it is extremely difficult to obtain in a pure state, so its chemistry is not very well known.
