Does graphite forms a molecular solid
WebIn graphite, each carbon atom forms three covalent bonds, leaving one electron per a carbon atom not used in bonding, which are delocalised and free to move throughout the structure. Whereas, in diamond, each carbon atom forms four covalent bonds, therefore there are no delocalised electrons. Explain why diamond is a hard substance, whereas ... http://molecularrecipes.com/RyTc/why-does-silicon-nitride-have-a-high-melting-point
