Silicon - Academic Dictionaries and Encyclopedias
Silicon is a semiconductor, readily either donating or sharing its four outer electrons, allowing for many different forms of chemical bonding. Even though it is, similar to carbon, a relatively inert element, silicon still reacts with halogens and dilute alkalis, but most acids (except for some hyper-reactive coinations of nitric acid and hydrofluoric acid) have no known effect on it.
Aluminium - University of Denver
2002/11/7· The useful wrought alloys contain 1-7% magnesium and 1% manganese. Its crystal form is face-centered cubic, with lattice constant a = 0.404 nm, and nearest-neighbor spacing of 0.286 nm. The familiar strong aluminium alloy Duralumin should really be Düralumin, since it was originally the product of the Dürener Metallwerke in Germany.
