Diamond and carbon
WebIn diamonds, each carbon atom is strongly bonded to four adjacent carbon atoms located at the apices of a tetrahedron (a three-sided pyramid). The four valence electrons of each carbon atom participate in the formation of very strong covalent bonds. These bonds have the same strength in all directions. This gives diamonds their great hardness. WebDiamond crystal is composed of four tetrahedral sp 3-hybridised carbon atoms and is the hardest known substance in nature, while graphite is composed of sp 2-hybridised …
