Title: Graphing Practice:
The Relation of Atomic Number and Atomic Mass
Purpose:
- to practice graphing
- to determine the
relation of atomic number and atomic mass
Materials:
- periodic chart
- ruler
- pencil
- graph paper
Procedure:
- Graph atomic number
(x) vs atomic mass (y) for elements 1~85
- Draw a line of best
fit
- Determine the slope
of the line
- Determine the percent
error (get actual value from Mrs. Nuņo)
Results: This will
be your graph
Analysis & Discussion:
- Summarize what you
did
- Describe the pattern
- Discuss what the
slope means
Conclusion:
- a one sentence testable
statement
- relate the atomic
number to the atomic mass
