Even though Earth and other terrestrial planets are exceptionally silicon-rich and carbon-poor (silicon is roughly 925 times more abundant in Earth's crust than carbon), terrestrial life bases itself on carbon. It may eschew silicon because silicon compounds are less varied, unstable in the presence of water, or block the flow of heat. [19]
NA32, "Investigation of Charm Production in Hadronic Interactions Using High - Resolution Silicon Detectors", was a research project at CERN.The project was approved on 18 November 1982, data taking completed on 20 August 1986 and the analysis of the results was formally considered finished on 20 August 1996.
As the CDMS-experiment has multiple different detector technologies in use, in particular, 2 types of detectors based on germanium or silicon, respectively, the experiments derived from some specific configuration of the CDMS-experiment detectors and different data-sets thus collected are sometimes given names like CDMS Ge, CDMS Si, CDMS II Si ...
The number of possible isomers increases rapidly with the number of silicon atoms. The members of the series (in terms of number of silicon atoms) follow: silane, SiH 4, 1 silicon atom and 4 hydrogen atoms, analogous to methane; disilane, Si 2 H 6 or H 3 Si−SiH 3, 2 silicon atoms and 6 hydrogen atoms, analogous to ethane
When silicon is grown by the Czochralski method, the melt is contained in a silica crucible. During growth, the walls of the crucible dissolve into the melt and Czochralski silicon therefore contains oxygen at a typical concentration of 10 18 cm −3. Oxygen impurities can have beneficial or detrimental effects.

It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others.
