Nanómetro

The video introduces nanotechnology and nanomaterials, focusing on the scale of structures involved, which are typically a few nanometers. It explains that this scale is comparable to that of atoms and molecules, with a typical atom having a diameter of about one-third of a nanometer.

What is the primary focus of nanotechnology?

• The study of large-scale structures

• The manipulation of materials at the atomic and molecular scale

• The development of new chemical compounds

• The exploration of outer space

At what scale do nanotechnology structures typically exist?

• Millimeters

• Meters

• Nanometers

• Centimeters

Which of the following best describes the scale of atoms and molecules?

• Micrometers

• Nanometers

• Kilometers

• Gigameters

What is the approximate size of a typical atom?

• 1 millimeter

• 1/3 of a nanometer

• 1 centimeter

• 1 meter

How does the size of a typical atom compare to a nanometer?

• It is smaller than a picometer

• It is exactly one nanometer

• It is about 1/3 of a nanometer

• It is larger than a nanometer
