Silicon has a melting point of 1420 °C and a boiling point of 2600 °C.Which state of matter would silicon be with a temperature of 3450 °C?SolidLiquidGas

Deduce the reason why silicon dioxide has high melting point, taking into consideration what you know about it's structure and type of bonding.

Silicon dioxide, SiO2 , and silicon(IV) chloride, SiCl4 , are both covalently bonded compounds.The table shows the melting and boiling points of these two compounds, and the physical state of silicon dioxide at room temperature. Compound Melting point in °C Boiling point in °C Physical state at room temperature SiO2 1710 2230solid SiCl4 −6958(i) Complete the table by giving the physical state of silicon(IV) chloride at room temperature. (1)(ii) Explain, in terms of structure and bonding, why silicon dioxide has a much higher melting point than silicon(IV) chloride.(6)
