chro·mi·um

 (krō′mē-əm)
n. Symbol Cr
A lustrous, hard, steel-gray metallic element, resistant to tarnish and corrosion and found primarily in chromite. It is used in the hardening of steel alloys and the production of stainless steels, in corrosion-resistant decorative platings, and as a pigment in glass. Atomic number 24; atomic weight 51.996; melting point 1,907°C; boiling point 2,671°C; specific gravity 7.15; valence 2, 3, 6. See Periodic Table.

[From French chrome; see chrome.]
