Characteristics and historyEdit

Silicon has an atomic mass of 28.086. This element was discovered by Humans for the first time in Earth's European continent in the year 1823, in Sweden. (ST reference: Star Fleet Medical Reference Manual)

When heated, silicon can form glass. (ST reference: Star Fleet Medical Reference Manual; TOS novel: The Pandora Principle)

Silicon-based lifeforms were considered a fantasy by the Federation until first contact with the silicon-based Horta of Janus VI in 2267. (TOS episode & Star Trek 4 novelization: The Devil in the Dark)

In 2370, when Julian Bashir was attempting to locate a Horta in the mines of Davonia, his tricorder had trouble singling it out as the mines had been drilled with high-powered phasers causing the walls to turn into glass, making the silicon lifeform difficult to detect amongst all the other silicon in the area. (DS9 novel: Devil in the Sky)
