- Like carbon, silicon will burn vigorously in oxygen if ignited to produce silica: Si(s) + O2(g) = SiO2(s) Silicon ignites if heated to temperatures around 1000°C. But saying that silicon can't exist in an oxygen environment is like saying a charcoal briquet can't exist in air.

Is Silicon Dioxide Safe? Silicon dioxide is one such ingredient, found in many products, though often misunderstood. Silicon dioxide (SiO 2), also known as silica, is a natural compound made of two of the earth’s most abundant materials: silicon (Si) and oxygen (O 2). Most often recognized in the form of quartz, silicon dioxide is found naturally in water, plants, animals, and within the Earth. The Earth’s crust is 59 percent silica, and it makes up more than 95 percent of known rocks on the planet.

- Silicon. Elemental silicon was prepared for the first time by Berzelius, in 1823, who placed silicon tetrafluoride in the presence of warm potassium. However, it was thought that Gay-Lussac and Thenard had already tried to obtain the amorphous silicon by the same method, in 1809. The substance obtained by Berzelius was a purer product as a result of exhausting filtering.

- Unlike organic polymers, which contain chains of carbon atoms in their structural backbones, a silicone’s backbone is composed of an alternating chain of silicon and oxygen atoms. Often organic, or carbon-containing, groups are attached to the sides of the silicon atoms (see organic chemistry). By adjusting the length of this silicon-oxygen chain, scientists can produce silicones in the form of fluids, resins, or elastomers (rubbers).

- Silicates. The fundamental structural unit is the silicon and oxygen tetrahedron. The four oxygens sit on the corners of the tetrahedon and the silicon sits at the center. These tetrahedra can be arranged in various ways by sharing one or more oxygens between adjacent tetrahedra. There are some 3,500 recognized minerals found on Earth. For our purpose, we can focus on about a dozen.

Silicon dioxide Silicon dioxide, also known as silica (from the Latin silex), is a chemical compound that is an oxide of silicon with the chemical formula Si O 2. It has been known since ancient times.Silica is most commonly found in nature as quartz, as well as in various living organisms.ilicon–oxygen bond lengths vary between the different crystal forms, for example in α-quartz the bond length is 161 pm, whereas in α-tridymite it is in the range 154–171 pm. The Si-O-Si angle also varies between a low value of 140° in α-tridymite, up to 180° in β-tridymite. In α-quartz the Si-O-Si angle is 144°.

- A silicon–oxygen tetrahedron is the SiO4 anionic group, or a silicon atom with four surrounding oxygen atoms arranged to define the corners of a tetrahedron. This is a fundamental component of most silicates in the Earth's crust. A variety of silicate minerals can be identified by the way that the tetrahedra links differ, also by the cations present in the mineral.
