nonmetallic element, 1817, coined by British chemist Thomas Thomson from silica (silicon dioxide), from which it was isolated. The name is patterned on carbon, etc. Silicon chip is attested from 1965; Silicon Valley for the Santa Clara Valley near San Francisco is attested by 1974, in reference to the concentration there of manufacturers of silicon chips used in computers, watches, etc.
1812, coined by English chemist Sir Humphry Davy, from alumina, alumine, the name given by French chemists late 18c. to aluminum oxide, from Latin alumen "alum" (see alum). Davy originally called it alumium (1808), then amended this to aluminum, which remains the U.S. word. British editors in 1812 further amended it to aluminium, the modern preferred British form, to better harmonize with other metallic element names (sodium, potassium, etc.).
Aluminium, for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound. [Quarterly Review, September 1812]
Aluminum foil attested by 1859; popularized in food packaging from c. 1950.
