Nanomaterials have large fraction of surface atoms.
Question
Nanomaterials have large fraction of surface atoms.
Solution
Yes, nanomaterials do have a large fraction of surface atoms. This is due to their small size, which results in a high surface area to volume ratio. Here's a step-by-step explanation:
-
Nanomaterials are materials that have at least one dimension (height, width, or length) that is less than 100 nanometers. A nanometer is one billionth of a meter.
-
At this scale, the properties of materials can change significantly from those at larger scales, which is primarily due to the relative increase in surface area.
-
When the size of material decreases, the surface area relative to the volume increases. This means that a larger proportion of atoms are found on the surface of the material rather than inside.
-
The atoms on the surface of a material can interact with the environment, which can lead to different properties. For example, nanomaterials can be more reactive or have greater strength than the same materials at larger scales.
-
Therefore, due to their small size and high surface area to volume ratio, nanomaterials have a large fraction of surface atoms.
