What Are the Properties of Silicon?

Silicon (called silicon x in Taiwan and Hong Kong) is a chemical element, and its chemical symbol is Si, which was formerly called silicon. The atomic number is 14, the relative atomic mass is 28.0855, and there are two allomorphs of amorphous silicon and crystalline silicon, which belong to the third period of the periodic table of the element, a metalloid element of group IVA. Silicon is also a very common element. However, it rarely appears in nature as a simple substance, but it is widely present in rocks, gravel, and dust in the form of complex silicates or silicas. The reserve of silicon in the universe ranks eighth. In the earth's crust, it is the second most abundant element, constituting 26.4% of the total mass of the earth's crust, second only to the first place oxygen (49.4%).
