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.]

The Captus 3000 also features a new software package that enables the system to perform a variety of additional tests, including Quality Assurance, Wipe Testing, Bioassay, Multichannel Analyzer and Lab Tests, including Schilling, Red Blood Cell (RBC) Survival, and I-125 and Chromium-51 (Cr-51) Blood Volume.
At the Gran Sasso underground laboratory in Italy, GALLEX researchers looked for low-energy neutrinos produced by the decay of chromium-51, a specially prepared, highly radioactive isotope of chromium.
In the experiment, neutrinos from the decay of chromium-51 interacted with gallium atoms to convert them into germanium-71 atoms.
