A reported silicon phosphide is Si 12 P 5 (no practical applications), [89] [90] formed by annealing an amorphous Si-P alloy. The arsenic–silicon phase diagram measured at 40 Bar has two phases: SiAs and SiAs 2. [91] The antimony–silicon system comprises a single eutectic close to the melting point of Sb. [92] The bismuth system is a ...
Silicon compounds are compounds containing the element silicon (Si). As a carbon group element, silicon often forms compounds in the +4 oxidation state, though many unusual compounds have been discovered that differ from expectations based on its valence electrons, including the silicides and some silanes. Metal silicides, silicon halides, and ...

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
Silicon and carbon are similar atoms. They lie above and below each other in the same group on the periodic table, and both have an s 2 p 2 electronic structure. The 2D structures of silicene and graphene also are quite similar, but they have important differences.
Silicon-34 is a radioactive isotope with a half-life of 2.8 seconds. [1] In addition to the usual N = 20 closed shell, the nucleus also shows a strong Z = 14 shell closure, making it behave like a doubly magic spherical nucleus, except that it is also located two protons above an island of inversion .

The silicon to hydrogen bond is longer than the C–H bond (148 compared to 105 pm) and weaker (299 compared to 338 kJ/mol). Hydrogen is more electronegative than silicon hence the naming convention of silyl hydrides. Commonly the presence of the hydride is not mentioned in the name of the compound. Triethylsilane has the formula Et 3 SiH.
