Graphite forms
WebHowever, each carbon atom in graphite forms just three covalent bonds with other carbon atoms. This creates a trigonal planar arrangement as predicted by electron pair repulsion theory, which you’ll learn more about in Shapes of Molecules. The angle between each bond is . The carbon atoms form a 2D hexagonal layer almost like a sheet of paper. WebGraphite is also said to be one of the naturally-occurring forms of crystalline carbon. However, this mineral is an interesting one and is commonly referred to as the mineral of all extremes. As such, Graphite is soft in nature, it cleaves easily even with light pressure, is greasy and features low specific gravity.
