Scandium is a chemical element with the symbol Sc and atomic number 21. It is a soft, silvery-white transition metal that serves as the first element in the third period of the d-block in the periodic table.

Discovered in 1879 by Swedish chemist Lars Fredrik Nilson through spectral analysis of the minerals euxenite and gadolinite, scandium was named after Scandia, the Latin name for Scandinavia, where the discovery minerals originated.

Although classified as a rare earth element alongside yttrium and the lanthanides due to similar chemical properties, scandium is not part of the lanthanide series and is relatively abundant in the Earth’s crust at approximately 22 parts per million (ppm), making it the 31st most common element by crustal abundance.

It occurs primarily in trace amounts dispersed in over 800 mineral species, including rare earth-bearing minerals like monazite and xenotime, but is rarely concentrated enough for direct mining; commercial production is limited, with global output of approximately 30–40 metric tons in 2023 (rising to about 40 tons in 2024), mainly as a by-product of uranium, titanium, or rare earth processing.

Scandium is a soft, silvery-white transition metal that develops a yellowish or pinkish cast upon exposure to air due to surface oxidation. It is relatively lightweight among metals, with a density of 2.99 g/cm³ at 20°C, making it comparable to aluminum in mass but stronger in certain alloys.

The element exhibits a high melting point of 1541 °C (1814 K) and a boiling point of 2836 °C (3109 K), indicating significant thermal stability suitable for high-temperature applications.

In its solid state at standard temperature and pressure, scandium adopts a hexagonal close-packed (hcp) crystal structure with lattice parameters a = 330.9 pm and c = 526.8 pm at 20°C.

This structure contributes to its ductility and malleability, though scandium is softer than many transition metals, with a Mohs hardness of approximately 2.5. Mechanically, it has a Young’s modulus of 74 GPa, reflecting moderate stiffness, and a Poisson’s ratio of 0.279.

Scandium demonstrates good thermal conductivity of 15.8 W/(m·K) at 300 K, which supports its use in heat-resistant materials. Its electrical resistivity is 562 nΩ·m at room temperature, indicating moderate conductivity for a metal. The coefficient of thermal expansion is 10.2 × 10⁻⁶ K⁻¹, showing low expansion under heat.
