Questions:
1. Analyze the following chart on the Metric System. Express the uncertainty of 19 trillionths of a meter in scientific notation
2. Compare the uncertainty shown above with the diameter of an atom.
a. To which percent of the atomic diameter can the three dimensional position of an array of atoms be represented by an image? How many atomic layers can potentially be measured within the uncertainty?
3. Research the topic of defects in crystals. Make a Concept Map of flowchart of the different types of defects, or provide definitions with pictures. How many types of defects can be encountered? What are the benefits of having defects in materials? Can you think of disadvantages?
4.
a. Describe the meaning of an amorphous material. Give one example of an amorphous material from your everyday life.
b. Provide a chart of at least 4 properties of amorphous materials and crystalline materials. Can a crystalline material present areas or volumes of amorphous structure? Provide an example.
4. An electron can be a wave or a particle ( particle-wave duality, according to De Broglie Hypothesis).
