Is Silicon A Metal, Silicon Periodic Table

 

Silicon is a chemical element. Its symbol in the chemical formula expression is “Si” which is present in sand and glass and which is the best known semiconductor material in electronic components. The atomic weight of the most common isotope is 28. [ Is Silicon A Metal] In its pure state, silicon is a metal-like substance and somewhat similar to aluminum. In its natural state, silicon appears as compounds bound with other elements. It is abundant in the earth’s crust. 

Silicon conducts electricity to a degree that depends on the degree to which impurities are added. The addition of impurities to silicon or any semiconductor material is called doping. 

Some impurities produce n-type silicon, in which most of the charge carriers are negatively charged electrons. Other impurities result in the production of p-type silicon, in which the majority of the charge carriers are positively holed s. Most silicon devices contain both n-type and p-type materials. 

Silicones provide many benefits to the products in which they are used, including enhanced flexibility and resistance to moisture, heat, cold and ultraviolet radiation. Silicones can be manufactured in many forms, including solids, liquids, semi-viscous pastes, greases, oils and rubbers. 

 

Is Silicon A Metal?

A term used in classification. Each element in the periodic table can be classified into a metal or a nonmetal category on the basis of its chemical and physical properties. Some elements having properties of both are classified as metalloids. In which silicon is placed in the category of a metalloid.

Silicon Periodic Table 

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, ( Is Silicon A Metal) brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table.

Industrial Uses of Silicone 

Silicone is used in the manufacture of waterproof clothing and paper. If a paper or cloth is exposed to silicone vapors, a thin layer of it spreads over the paper or cloth thus making it waterproof. 

Greases such as Vaseline made from silicone do not freeze even at -40°C, so they are used as lubricants in aircraft. Aircraft fly from very high ground temperature to sky high where the temperature is very low, so it is useful to have a lubricant that does not dilute at very high temperature and does not solidify even at very low temperature, silicone grease Complies with all these conditions and is therefore used as a lubricant in aircraft. 

Silicone rubber becomes of such a nature after necessary vulcanization that its shape and elasticity become permanent, hence they are used in many important places. Silicone rubber window gaskets are made in spacecraft and jet aircraft to protect buildings from damping and to make them airtight. The Apollo astronauts, who stepped on the surface of the Moon with a very different temperature, wore shoes made of silicone rubber soles. Astronauts’ costumes are also made from silicone. 

Since silicon does not burn black even at very high temperatures, it is used as an insulator in electric motors and other electrical equipment. If a little silicon is added to the paints, then they do not fade due to sunlight, water, heat etc., so they remain good for a long time.
