The element was discovered by Nilson in 1878
in the minerals euxenite and gadolinite, which
had not yet been found anywhere except in
Scandinavia.
Scandium is apparently a much more abundant
element in the sun and certain stars than here on
earth. It is about the 23rd most abundant element
in the sun, compared to the 50th most abundant on
earth.
Little is known about scandium so it is handled
with care.
