Question
Explain why giant covalent structures are solids with very high melting points.
Answer
Giant covalent structures are solids because they consist of a vast network of atoms bonded together by strong covalent bonds. These bonds require a significant amount of energy to break, resulting in very high melting points.
Explanation
This answer is strong because it directly addresses the relationship between the structure of giant covalent substances and their physical state and melting points. The question tests the understanding of bonding and structure in relation to properties.
Common mistake
Misunderstanding melting points
Students often think that giant covalent structures have low melting points because they are made of non-metal atoms.
Emphasize that giant covalent structures are held together by many strong covalent bonds, which require a lot of energy to break, resulting in very high melting points.
