...–1829) discovered chromium oxide in an ore of “red lead” from Siberia. The following year, he isolated the new metal, chromium, by the heating of chromium oxide and charcoal. He called the metal chrome for the Greek word chromos , meaning color, after observing that most of the compounds of chromium...
