Introduction to Nanoparticles | GCSE Chemistry Practice
Nanoparticles have a very high surface area to volume ratio, giving them unique properties.
How many atoms are typically in a nanoparticle?
What is Introduction to Nanoparticles | Practice?
"A microscopic particle whose size is measured in nanometres."
Question 1
What is the typical size range of a nanoparticle?
Question 2
As the side of a cube decreases tenfold, what happens to its surface area to volume ratio?
Question 3
Why might nanoparticles be more effective catalysts than bulk materials?
Nanoscience Basics
Size: 1nm to 100nm.
High Surface Area to Volume Ratio makes them very reactive.
Used in sunscreens, catalysts, and medicine.
Exam Tip
Math Link: As particle size decreases by 10, the SA:V ratio increases by 10.
