Planetary Bohr Model ng Cobalt (Co)
Description
Hard, ductile, lustrous bluish-gray metal. Exists in the earth's curst in cocentrations of about 25 ppm. It has remarkable magnetic properties.
Uses
Used in many hard alloys; for magnets, ceramics and special glasses. Remains hard up to 982°C. Radioactive cobalt-60 is used in cancer therapy.
Sources
Occurs in compounds with arsenic, oxygen and sulfur as in cobaltine (CoAsS) and linneite (Co3S4). Pure cobalt is obtained as a byproduct of refining nickel, copper and iron.
Pronounciation (English)
KO-bolt
