means A hard, brittle, grayish semi-metal (atomic number 14) that, when refined and precisely doped with impurities, becomes the semiconducting foundation of computer chips.

from From Latin 'silex,' meaning flint or hard stone — the same root that gives us 'silica.' The element was first isolated in the early 1800s and named for its presence in silica (sand and quartz are mostly silicon dioxide). The '-on' ending was chosen to echo other nonmetals like carbon and boron, marking it as a related elemental cousin rather than a metal. Note: it's distinct from 'silicone,' the rubbery polymer — a common mix-up, but a different word for a different substance.
