Silicon is an
element with atomic number 14, symbol Si.
It has three stable Isotopes.
Silicon is synthesized by Oxygen Burning
and the Alpha Process, in large stars
and in supernovae. Silicon Spectral Lines
are sometimes used in Metallicity studies.
Silicon Burning is essentially the alpha process
applied to silicon, which at the hottest temperatures
in massive stars produces the heaviest common
elements, Nickel and Iron.
