In 1879, Lars Fredrik Nilson and his team detected scandium in the minerals euxenite and gadolinite.

Nilson prepared 2 grams of scandium oxide of high purity.

Per Teodor Cleve showed that scandium had properties similar to those predicted by Mendeleev for eka-boron.

Metallic scandium was first prepared in 1937 by Fischer and his colleagues. Z latinského slova Scandia, skandinávie 32 1886 Clemens Winkler Germany From the Latin word "Germania" meaning "Germany"

Scandium is considered to be of low toxicity
The stable form of scandium is created in supernovas via the r-process
Scandium is used in sports equipment such as golf iron shafts, baseball bats, bicycle frames and fishing rods.

Scandium iodide, along with sodium iodide, when added to a modified form of mercury-vapor lamp, produces a form of metal halide lamp.

The radioactive isotope 46Sc is used in oil refineries as a tracing agent.
