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).
Native elements are minerals that contain only atoms of one type of element. The elements are not combined with other elements. In nature most elements are combined with other elements to form chemical compounds. So, the native elements mineral group contains a relatively small number of minerals. One mineral contains the elements zinc, carbon, and oxygen. 2  The other mineral contains the elements zinc, silicon, oxygen, and hydrogen. 3  Your friend tells you that the minerals are in the same mineral group.
