Facts about Scandium:
- Scandium: Scandium is silvery white in colour and reacts with air and water.
- Fun fact about Scandium: Aluminium-Scandium alloys is used for sports equipment that needs to be strong and light weight. Such as bicycle frames, fishing rods, golf iron shafts and baseball bats.
- Chemical symbol: Sc
- Atomic number: 44.96
A crystal structure containing Scandium:
Structure of a hexa-coordinated colourless complex of Scandium 3+ ions
Facts about this structure:
- Formula: C6 H14 Cl3 O3 Sc
- Structure name: Trichloro-(2,5,8-trioxononane)-scandium
- Fun fact about the structure: This is a hexacoordinated Scandium complex. Even though Scandium is a member of the 3D block of elements this crystal is colorless, as most Scandium complexes are.
- CSD refcode: CORNIG (What’s this?)

Scandium is the first member of the 3D block elements and the first rare earth elements. Scandium exhibits +3 oxidation state. In Sc3+ state, it has a completely empty 3D sub-shell. For this reason, generally Scandium complexes are colourless. Scandium is also not a transition metal in the true sense since it cannot exist in wide variety of transition states. Scandium has also no known biological role and is a suspected carcinogen.
