Scandium

Description:
Scandium is a chemical element with the symbol Sc and atomic number 21. It is classified as a transition metal and is part of the d-block of the periodic table. Scandium is characterized by its silvery-white appearance and relatively lightweight nature. It has a melting point of approximately 1541°C and a boiling point around 2836°C, indicating its stability at high temperatures. Scandium is known for its low density and high strength, making it valuable in aerospace and sporting equipment applications. Chemically, it exhibits a +3 oxidation state, forming various compounds, including oxides and halides. Scandium is relatively rare in the Earth's crust and is primarily obtained from minerals such as thortveitite and euxenite. It has limited biological significance, but it is considered non-toxic and has been studied for potential applications in medicine and technology. Due to its unique properties, scandium is often alloyed with aluminum to enhance strength and corrosion resistance.
