Each carbon atom has a bond with four other carbon atoms. Motivational and inspirational sources to all those parents to enjoy life with their babies, Home FAQ Why Does Silicon Have A High Melting Point. Electron bonding or bonds formed by free ions inside a metal is what determines its high melting point. Boron does not generally make ionic bonds, it forms stable covalent bonds. Whereas the solid state has been traditionally considered to be of little synthetic value by the broader community of synthetic chemists, the solid-state . In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point. $\begingroup$ As u said covalent atoms are harder to break due to mutual sharing of electrons, the silicon would be expected to have a higher boiling point however it doesn't. Why does silicon dioxide have a higher melting point than sulfur trioxide? its melting point is extremely high in degrees Celsius as it has This means that it forms thousands of covalent bonds between its silicon and oxygen subunits.
