Silicon - Wikiwand Silicon is the eighth most common element in the universe by mass, but very rarely occurs in its pure form in the Earth's crust It is widely distributed throughout space in cosmic dusts, planetoids, and planets as various forms of silicon dioxide (silica) or silicates
Isotopes of silicon - Wikipedia Silicon (14 Si) has 25 known isotopes, with mass number ranging from 22 to 46 28 Si (the most abundant isotope, at 92 24%), 29 Si (4 67%), and 30 Si (3 07%) are stable The longest-lived radioisotope is 32 Si, which occurs naturally in tiny quantities from cosmic ray spallation of argon Its half-life has been determined to be approximately 157 years; it beta decays with energy 0 21 MeV to 32
Silicon - Electronics, Solar Cells, Alloys | Britannica Silicon’s atomic structure makes it an extremely important semiconductor (see crystal: Electric properties), and silicon is the most important semiconductor in the electronics and technology sector
Silicon - Simple English Wikipedia, the free encyclopedia Its atomic number is 14 on the periodic table Its symbol is Si It is a hard, brittle crystalline solid It is a tetravalent metalloid and semiconductor It is a member of group 14 in the periodic table Silicon looks like a metal, but cannot do everything that a metal can, like conduct electricity well
silicon summary | Britannica silicon, Nonmetallic to semimetallic chemical element, chemical symbol Si, atomic number 14 Second only to oxygen in abundance in Earth’s crust, it never occurs free but is found in almost all rocks and in sand, clay, and soils, combined with oxygen as silica (silicon dioxide, SiO 2) or with oxygen and metals as silicate minerals
