Scandium

Scandium is a chemical element with the symbol Sc and atomic number 21. It is a silvery-white metallic transition metal that is found in rare earth minerals and is used in aerospace and defense industries due to its high melting point, strength, and light weight. Scandium is also used in the production of high-intensity lamps, lasers, and sports equipment such as baseball bats and bicycle frames. In space and astronautical engineering, scandium is used in the construction of spacecraft and satellites due to its ability to withstand extreme temperatures and radiation exposure.
