- Carbon is a nonmetal, and silicon is a metalloid. - Carbon and silicon have the same common electron configuration as s 2, p 2. But in silicon, the electrons are spread into the 3rd energy level, whereas in carbon it is only to the 2nd energy level.
1 Silicon is the eighth most abundant element in the Universe; it is made in stars with a mass of eight or more Earth suns. 2  Near the end of their lives these stars enter the carbon burning phase, adding helium nuclei to carbon to produce oxygen, neon, magnesium and silicon.mpurities in the silicon are about 1 part per billion or less. Isotopes: Silicon has 14 isotopes whose half-lives are known, with mass numbers 22 to 36. Naturally occurring silicon is a mixture of its three stable isotopes and they are found in the percentages shown: 28 Si (92.2%), 29 Si (4.7%) and 30 Si (3.1%).
