Bulk and surface properties of matter including nanoparticles (chemistry only)
Question
- A. They can be toxic to living organisms
- B. They are always more effective than bulk materials
- C. They have no environmental impact
- D. They are larger than fine particles
Answer
The correct option is They can be toxic to living organisms. This answer is correct because it matches the approved learning objective to (chemistry only) Explain possible risks associated with nanoparticle use in the subtopic Uses of nanoparticles.
Explanation
The correct option is They can be toxic to living organisms. They can be toxic to living organisms is correct because it directly supports the approved learning objective to (chemistry only) Explain possible risks associated with nanoparticle use. This belongs to the subtopic Uses of nanoparticles within Bulk and surface properties of matter including nanoparticles (chemistry only), so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Uses of nanoparticles.
Common mistake
Misunderstanding Risks
Students often believe that nanoparticles are completely safe and pose no risks.
Students should research and explain the potential risks associated with nanoparticle use, including environmental and health concerns.
