Its dioxide is found in quartz, and this element is useful for making the semiconductors used in computer chips.
A common method for calibration in NMR uses the tetramethyl compound of this element. Types of minerals that contain this element bonded to oxygen are known as pyroxenes and olivine. It is used to make a protective shell by diatoms (DYE-uh-tomz). N and P type substances can be made by adding arsenic and gallium to it in a process known as doping. Its dioxide is found in quartz, and this element is useful for making the semiconductors used in computer chips. For 10 points, name this element with atomic number 14 and symbol Si.
