What are 3 uses for scandium?
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry.
Why is scandium named scandium?
Lars Fredrik Nilson and his team detected this element in the minerals euxenite and gadolinite in 1879. Nilson prepared 2 grams of scandium oxide of high purity. He named the element scandium, from the Latin Scandia meaning “Scandinavia”.
What is the original name of scandium?
History. Russian chemist Dmitri Mendeleev, inventor of the periodic table, predicted the existence and properties of scandium (which he called “ekaboron” — similar to boron) in 1869, according to the New World Encyclopedia.
Is scandium harmful to humans?
Health effects of scandium Scandium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
Who produces scandium?
Scandium was recovered from titanium, zirconium, cobalt, and nickel process streams. China, the Philippines, and Russia were the leading producers.
What is scandium element family?

What is the color of scandium?
silvery white
scandium (Sc), chemical element, a rare-earth metal of Group 3 of the periodic table. Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc2O3 oxide on the surface.
