一种出乎意料的硅化合物硅与碳在周期表上属同一族，都具有４个可供利用的键电子。在单键中，硅或碳原子为该键提供一个电子，故能与４个邻近原子形成单键。除形成单键外，碳原子能提供２个或甚至３个电子以与邻近原子之一结合，形成双键或三键。根据传统化学理论，硅原子... An unexpected silicon compound, silicon and carbon belong to the same family on the periodic table, each with four available bond electrons. In a single bond, a silicon or carbon atom provides one electron for the bond and therefore forms a single bond with four adjacent atoms. In addition to forming a single bond, a carbon atom can provide two or even three electrons to combine with one of the adjacent atoms to form a double or triple bond. According to the traditional chemical theory, silicon atoms ...
