GCSE Chemistry Revision "Diamond and Silicon Dioxide"
Freesciencelessons・2 minutes read
Giant covalent molecules like diamond and silicon dioxide have high melting and boiling points because of the numerous strong covalent bonds they contain. These molecules, such as diamond composed of carbon and silicon dioxide made of silicon and oxygen, exhibit exceptional hardness and inability to conduct electricity due to their unique covalent bonds.
Insights
- Giant covalent molecules like diamond and silicon dioxide exhibit high melting and boiling points because of the multitude of strong covalent bonds they possess, necessitating significant energy for bond breakage.
- Diamond's exceptional hardness and inability to conduct electricity stem from its unique structure of carbon atoms forming covalent bonds with each other, while silicon dioxide's similar properties are attributed to the strong covalent bonds between silicon and oxygen atoms.
