Question
Explain why graphene is an excellent conductor of electricity.
Answer
Graphene conducts electricity due to the presence of delocalised electrons. Each carbon atom in graphene forms three covalent bonds, leaving one electron free to move throughout the structure, allowing for efficient electrical conduction.
Explanation
This question tests the student's understanding of the relationship between the structure of graphene and its properties, specifically its electrical conductivity. The answer highlights the role of delocalised electrons in facilitating conduction.
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.
