Brief description |
| |
Scandium has a melting point of 1541 °C, boiling point of 2830 °C, specific gravity of 2.989 (25 °C), and valence of 3. It is a silvery-white metal which develops a yellowish or pinkish cast when exposed to air. Scandium is a very light, relatively soft metal. Scandium reacts rapidly with many acids. The blue color of aquamarine is attributed to the presence of scandium.
