 ChemLab #7 - Ionization Energy |
| Date Submitted: |
Score: |
Your Name: This is an individual lab to be completed on your computer.
|
| The Lab Problem:
Graph the first ionization energy for elements 1 through 18. To best see the patterns, make this graph with a "connect-the-dots" line, not a "best-fit" line. No part of this lab is to be printed. |

Use your completed graph to answer the following questions:
- Describe any patterns you see on your graph.
- Do you see any relationship between the pattern of the graph and electron energy sublevels?
- How does this relate to what you know about the chemical activity of these elements?

Conclusion: Save the completed graph. Check your graph against this rubric to be sure it is complete. Show the completed graph to your facilitator, On The Computer Screen, for the conclusion for this lab. DO NOT print the graph unless told to do so.
