Question

1. On your graph paper, label the x-axis as "Atomic Number." Label the y-axis as "Atomic Mass." There are no units for atomic number, but atomic mass has a unit of (u). This stands for atomic mass units.
2. For each of the first 85 elements in the periodic table, plot a point representing the atomic number (x) and the atomic mass (y).
3. Answer the questions on your lab report.
Question:
What is the relationship between the atomic number and atomic mass of an element?
Prediction:
Make a prediction based on the question above. Be sure to give an explanation for your answer. (4 points)




Observations:
The graph you created will be used as your observations and results. Please attach it to this report. (8 points)

Summary:
Use your observations to answer the questions below.
1. Do your observations support your prediction? Explain how they do, or why they do not. (4 points)




2. Describe the shape of your graph. Does it look as you expected? (4 points)




3. Does your graph maintain a consistent pattern? Identify any changes you notice in the pattern. (4 points)




4. How would you describe the relationship between the atomic number and atomic mass of an element? (4 points)




5. Describe any challenges you encountered when making your graph. Could you have done anything differently? (4 points)




6. Why do you suppose the graph behaves as it does toward its right end? (4 points)




7. Radioactivity affects elements that are unstable and tend to break apart easily. These elements often have the largest atomic numbers on the periodic table. Explain how this relates to the behavior of the graph for the heaviest elements (those at the right end of the graph). (4 points)
