The shared electron pairs are held tightly in sigma bonds between adjacent atoms.”(“Carbon”, Encarta Online, 2001) The diamond structure is shown in Figure 1. Diamond ... WebDiamond: each carbon atom bonds to 4 other carbon atoms, WHILST, Graphite: each carbon atom bonds to 3 other carbon atoms. Thus, diamond bears more of a tetrahedral structure, whereas graphite takes the form of layers. The presence of layers means that atoms can slide over each other easily. grandform white space
