A hard, lustrous metallic element with the symbol Cr, known for its resistance to corrosion and its use in creating stainless steel and chrome plating. It produces various colored compounds.
From French chrome, from Greek χρῶμα (khrōma) meaning 'color,' referring to the many colorful compounds this element forms. The element was discovered in 1797 by French chemist Louis-Nicolas Vauquelin, who named it for the brilliant colors of its compounds. The '-ium' suffix was added to follow the naming convention for metallic elements.
Chromium literally means 'color element' because it forms compounds in almost every color of the rainbow - red, orange, yellow, green, blue, and purple! What's incredible is that this 'colorful' metal makes things colorless and shiny when used in chrome plating, proving that sometimes an element's most famous use is the opposite of what its name suggests.
