Silanes tend to be unstable because an Si-Si bond has a strength slightly lower than a C-C one. Oxygen decomposes silanes easily, as the silicon-oxygen bond is quite stable.
The nomenclature for naming silanes is regular, unlike alkanes. The name of each silane is given by a prefix for the number of silcon atoms (di, tri, tetra, penta, etc.) followed by the word silane. There is no prefix for one; it is understood.
Silanes can also be named like any other inorganic compound; in this naming system, silane would become silicon tetrahydride.
