Question
Describe the structure of graphene and how it contributes to its strength.
Answer
Graphene consists of a single layer of carbon atoms arranged in a two-dimensional hexagonal lattice. This arrangement allows for strong covalent bonds between the carbon atoms, contributing to its exceptional strength and rigidity.
Explanation
This question assesses the student's ability to connect the structural features of graphene with its physical properties. The answer emphasizes the significance of the hexagonal arrangement and covalent bonding in determining graphene's strength.
Common mistake
Misunderstanding Graphene's Conductivity
Students often state that graphene conducts electricity because it has a high number of carbon atoms.
Students should explain that graphene conducts electricity due to the presence of delocalised electrons that can move freely within its structure.
