Bulk and surface properties of matter including nanoparticles (chemistry only)
Question
- A. They have a different chemical composition
- B. They have a larger size
- C. They have a higher surface area to volume ratio
- D. They are made of different elements
Answer
The correct option is They have a higher surface area to volume ratio. This answer is correct because it matches the approved learning objective to (chemistry only) Compare nanoparticle dimensions with typical atom and molecule dimensions in the subtopic Sizes of particles and their properties.
Explanation
The correct option is They have a higher surface area to volume ratio. They have a higher surface area to volume ratio is correct because it directly supports the approved learning objective to (chemistry only) Compare nanoparticle dimensions with typical atom and molecule dimensions. This belongs to the subtopic Sizes of particles and their properties 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 Sizes of particles and their properties.
Common mistake
Sizes of particles and their properties correction for Misunderstandin
Students often confuse the size of nanoparticles with that of larger particles, thinking nanoparticles are similar in size to fine or coarse particles This error matters in Sizes of particles and their properties because it drifts away from the objective: (chemistry only) Compare nanoparticle dimensions with typical atom and molecule dimensions.
Correct it by naming the exact chemistry idea, using precise bonding or structure vocabulary, and linking the answer back to Sizes of particles and their properties. For this objective, students should (chemistry only) compare nanoparticle dimensions with typical atom and molecule dimensions.
