Silicate - Wikipedia

In most commonly encountered silicates, including almost all silicate minerals found in the Earth's crust, each silicon atom occupies the center of an idealized [tetrahedron] whose corners are four oxygen atoms, connected to it by single covalent bonds according to the octet rule. These tetrahedra may occur as isolated orthosilicate anions SiO 4−
