Bulk and surface properties of matter including nanoparticles (chemistry only)

Question

A. They are easier to handle.
B. They have a higher surface area to volume ratio.
C. They are less expensive to produce.
D. They are more stable in the environment.

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) Explain why nanoparticles can have different properties from the same material in bulk 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) Explain why nanoparticles can have different properties from the same material in bulk. 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

Misunderstanding Nanoparticle Properties

Students often think that nanoparticles have the same properties as the bulk material they are derived from.

Students should focus on how the size and surface area of nanoparticles can lead to different chemical and physical properties compared to the bulk material.
