Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
Dec 30, 2022 · silicone, also called polysiloxane, any of a diverse class of fluids, resins, or elastomers based on polymerized siloxanes, substances whose molecules consist of chains made of alternating silicon and oxygen atoms.

Silicon is a chemical element, a hard dark-grey semiconducting metalloid, which in its crystalline form is used to make integrated circuits ("electronic chips") and solar cells. Silicones are compounds that contain silicon, carbon, hydrogen, oxygen, and perhaps other kinds of atoms as well, and have many very different physical and chemical properties.
Jun 3, 2022 · Silicon, atomic symbol Si, has an atomic number of 14, below carbon and to the right of aluminum. This element is in the metalloid family and has four valence electrons. Hence, it is not a very reactive element. Silicon has an electronegativity of 1.9 (Pauling scale). Silicon’s typical electron configuration is 1s 2 2s 2 2p 6 3s 2 3p 2 .
Aug 27, 2019 · silicon (a naturally occurring element) oxygen; carbon; hydrogen; It’s usually produced as a liquid or flexible plastic. It’s used for medical, electrical, cooking, and other purposes.
Silicon is a naturally occurring mineral. It's the second-most abundant element on earth after oxygen. Food sources include water, fruits, and vegetables. Silicon supplements are sometimes used...
