Note: Currently, Si2 is not recognized as a chemical compound. Silicon (Si) is a chemical element, but it does not exist as Si2. Therefore, defining and describing Si2 is impossible.
However, we will provide information about Silicon (Si) so you can better understand this element.
Silicon (Si) is a chemical element in the periodic table, symbolized as Si with an atomic number of 14. Silicon is a very common non-metal element, accounting for about 27.7% of the Earth’s crust mass, mainly in the form of silicate salts. Silicon has an atomic mass of 28.0855.
Regarding its properties, Silicon is a crystal solid with a blue-gray color. It is odorless, tasteless, and insoluble in water. Silicon does not react with most acids but can react with strong acids such as HF.
Silicon participates in various chemical reactions. Some examples of these reactions include reacting with oxygen to form SiO2, reacting with chlorine to form SiCl4, and reacting with nitrogen to form Si3N4.
Silicon can be synthesized from silicate in the steelmaking process or from silicate ore by smelting with coal.
