Why does carbon have a higher melting point than silicon? Silicon is a non-metal, and has a giant covalent structure exactly the same as carbon in diamond – hence the high melting point. You have to break strong covalent bonds in order to melt it.
Why does carbon have the highest melting point in its period? Carbon atoms have four unpaired electrons and can form four covalent bonds. Each carbon is covalently bonded to three others, so there is one electron delocalised per carbon atom which is free to move between the layers and carry charge. Hence graphite conducts electricity. Like diamond it has a high melting point.
Does more carbon mean higher melting point? Higher melting and boiling points signify stronger noncovalent intermolecular forces. … More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points.
