Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).Silicate minerals also often contain other elements, such as calcium, iron, and magnesium.ilicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).
The most common group of rock-forming minerals is the __________. The silicon-oxygen tetrahedron is a complex ion. True. The ratio of silicon atoms to oxygen atoms is the same in each of the various silicate structures.
