Similarities Of Silicon & Carbon

Silicon and carbon are among the most similar elements on the periodic table. They have some major differences, such as silicon being an inorganic compound, but many of the compounds created using carbon or silicon are almost twins. Carbon is the element of life forms, playing a major role in metabolic processes, while silicon is an element of the machines, serving as a major component for parts, such as semiconductors.

Compounds

Both carbon and silicon commonly form compounds, easily sharing electrons with other elements. Carbon will make multiple bonds with other carbon molecules by forming single, double and triple covalent bonds. Carbon forms compounds such as methane, propane, butane, benzene and carbon dioxide. Silicon forms compounds such as silane, disilicon hexahydride, silicon tetrafluoride and silicon tetrachloride. Carbon and silicon are often combined, with carbon serving as silicon's backbone. However, silicon can also form silicon polymers, which are silicon and oxygen structures.

Periodic Table

Both carbon and silicon are members of the IVA family on the periodic table. Both carbon and silicon are non-metals. Silicon is only a little bit more metallic than carbon because it loses its electrons a little more easily. They both have a valence of 4. Carbon and silicon almost have the same density, with silicon having 2.3 grams per cubic centimeter and carbon having 2.2 grams per cubic centimeter. Both carbon and silicon are solids at room temperature.

Hardness

Both carbon and silicon have broader hardness ranges. One form of carbon, called graphite, is one of the softest elements known. Another form of carbon, the diamond, is one of the hardest substances known. The silicon carbide is almost as hard as a diamond, and both quartz crystals and buckyballs are also very hard. Silicon's mica is the silicon version of carbon's graphite.
