Left: SiO sub 4 tetrahedra. Basic unit of all silicate structure. Right: Si sub 2 O sub 7 (double Tetrahedral group). In silicate structures the silicon atoms group in fourfold symmetry with oxygen. The basic unit of all silicate structure is the tetrahedron. The sorosilicates possess double tetrehedral groups.

Muscovite. Oxygen: white. Silicon: small metallic spheres in centre of white tetrahedral oxygen groups, only one or two visible. Aluminum: larger metallic spheres. Potassium: purple OH groups, or hydroxyl: blue. A phyllosilicate.

Halite (cubo-octahedron). Sodium: yellow. Chlorine: green. The halite (and sylvite) structure is like that of the galena, and petraclase groups of minerals. One kind of ions (Cl, S, etc.) occupies the points of a face-centred cubic lattice while the other kinds of ions (Na, Pb, etc.) lie halfway between each pair of the first kind along (100) directions.
