💡 Exam Tips for Nanoparticles
🎯 Common Question Types:
- Define nanoparticle and give the size range (1-2 marks)
- Explain why nanoparticles are more reactive or better catalysts (2 marks)
- Describe an application of nanoparticles and why they are suitable (2-3 marks)
- Evaluate the benefits and risks of using nanoparticles (3-4 marks)
📝 Key Command Words:
- Explain: Reference "high surface area to volume ratio" for reactivity/catalyst questions
- Describe: Name the application and link the nanoparticle property to the function
- Evaluate: Give benefits (uses, effectiveness) AND risks (unknown health effects, potential toxicity)
- Define: 1-100 nm, high surface area to volume ratio, different properties from bulk material
⚠️ Common Mistakes to Avoid:
- Saying nanoparticles have the same properties as bulk material — they may have DIFFERENT properties
- Giving only benefits when asked to "evaluate" — always include health/safety risks
- Confusing nanoparticles with atoms or molecules — nanoparticles are collections of many atoms
- Forgetting the size range: 1-100 nm (not micrometres, not picometres)
- Saying fullerenes are giant covalent structures — they are discrete molecules (simple molecular)
