WebApr 7, 2024 · A phyllosilicate, which was previously known as a disilicate, is a compound with a structure in which the silicate tetrahedrons are arranged in sheets. Hence, they are also known as sheet silicates. In these sheet silicates, the central atom is silicon and is surrounded by four atoms of oxygen at the corners of a tetrahedron. WebThe silicates can be divided into groups according to structural configuration, which arises from the sharing of one, two, three, or all oxygen ions of a tetrahedron. Nesosilicates have isolated groups of SiO 4, while … WebAug 15, 2024 · A majority of the igneous rocks and sedimentary rocks are made of silicate minerals. The most common type of silicate is (SiO 4) 4-. There are many different types of silicates. Most of them have a general chemical formula of X x Y y (Z z O o )W w. X = +1 or +2 cations. Y = +2, +3, or +4 cations. Z = + 3 or +4 cations. O = oxygen. michelle ainsworth abc
