siliconn.

/ˈsɪlɪkən/

Etymology: < Latin silic- silex n.¹ Named by T. Thomson, in place of Sir H. Davy's silicium n.

A non-metallic element, which in respect of its abundance in the ground ranks next to oxygen, and is usually found combined with this as silica; it may be obtained in the form of powder, scales, or crystals. Chemical symbol Si.

1817 T. Thomson Syst. Chem. (ed. 5) I. 252 The base of silica has been usually considered as a metal, and called silicium. But..as it bears a close resemblance to boron and carbon, it is better to class it along with these bodies, and to give it the name of silicon.
