LaoSilicon has a higher boiling point than phosphorus because silicon forms a network structure held together by strong covalent bonds, which require more energy to break compared to the weaker van der Waals forces between phosphorus molecules. This results in silicon having a higher boiling point.

Does chlorine have a higher boiling point than iodine?
Yes, chlorine has a higher boiling point than iodine. Chlorine has a boiling point of -34.6 degrees Celsius, while iodine has a boiling point of 184 degrees Celsius.
What is the melting point of the element phosphorus?
The melting point of phosphorus is approximately 44.1 degrees Celsius.
Why aluminum trifluoride has high boiling point then silicon tetrafluoride which is a gas?
The higher boiling point of aluminum trifluoride compared to silicon tetrafluoride is due to the stronger intermolecular forces present in aluminum trifluoride. The aluminum atom can form stronger dipole-dipole interactions and van der Waals forces with neighboring molecules, leading to a higher boiling point. In contrast, silicon tetrafluoride exists as a gas due to its weaker intermolecular forces of attraction, resulting in a lower boiling point.
Why does silicon tetrachloride have a low boiling point?
Silicon tetrachloride has a low boiling point because it is a simple molecular compound with weak van der Waals forces between its molecules. These forces are easily overcome, leading to a lower boiling point compared to compounds with stronger intermolecular forces.
