Chapter 1, Problem 1QRT

Interpretation Introduction

Interpretation:

The term nanoscale has to be explained.  Also, the reason for importance of structure at nanoscale has to be given.

Explanation of Solution

• Nanoscale indicates something that is one billion times smaller than something else.
• Nanoscale involves anything with at least one dimension smaller than about $\text{100 nm}$.
• One nanometer (nm) is ${\text{1×10}}^{\text{-9}}\text{ m}$. 
• Structure at nanoscale is important because it is the key to the properties and reactivity of a molecule.
