A silica tetrahedron is composed of a central silicon cation surrounded by four SP3 bonded oxygen anions. The angle formed between the oxygen - silicon - oxygen ions (O-Si-O) varies between 140 and 180 degrees depending on the specific type of silica.

Which silicate mineral group has a double chain silicate?
A silicate mineral that shares it's oxygen atom with another silica tetrahedron, forming a chain of tetrahedra. Single chain silicates include a group called the pyroxenes.

tetrahedron...
The building blocks of the silicate minerals is called the what?
Silicate tetrahedra. The tetrahedra are spanned by oxigen atoms, and right in the middle, there is a silicon atom. The chemical formula for one silicate tetrahedron is SiO4 The actual rate between silicon and oxigen can change as the tetrahedra are linked together, as different tetrahedra can share an oxigen atom with eachother.
What is the term used to describe the basic building block of all silicate material?
silicate-oxygen tetrahedron

What are sheet silicates?
A structural type of silicate mineral in which flat sheets are formed by the sharing of three of the four oxygen atoms in each tetrahedron with neighboring tetrahedrons. Also known as layer silicate; sheet mineral; sheet silicate.
