Web1 jul. 2024 · Silicon has a high thermal conductivity and conducts heat well. Unlike metals, it's brittle, and not malleable or ductile. Like carbon, it usually has a valence of 4 (tetravalent), but unlike carbon, silicon can also form five or six bonds. Silicon is the second most abundant element on Earth by mass, making up over 27% of the crust. shanks character
