Hydride of silicon
The simplest isomer of a silane is the one in which the silicon atoms are arranged in a single chain with no branches. This isomer is sometimes called the n-isomer (n for "normal", although it is not necessarily the most common). However the chain of silicon atoms may also be branched at one or more points. The number of possible isomers increases rapidly with the number of s… Webproperties of silicon hydride clusters with up to 10 silicon atoms calculated using ab initio and group additivity methods, (2) rate parameters estimated based on linear free energy relationships and the reaction thermochemistry, and (3) formation of rings and polycyclic silicon hydride clusters. This allows us to identify

Like its neighbour aluminium, silicon forms a thin, continuous surface layer of silicon dioxide (SiO 2) that protects the metal from oxidation. Thus silicon does not measurably react with the air below 900 °C, but formation of the vitreous dioxide rapidly increases between 950 °C and 1160 °C and when 1400 °C is reached, atmospheric nitrogen also reacts to give the nitrides SiN and Si 3N 4.
