Part 2 - Unstable Isotopes
1. Complete the following table (2 points):
Unstable Isotope
Carbon-14
Silicon-32
Iron-52
Xenon - 135
Lead-214
Radium - 226
Atomic Protons Neutrons
Number (X axis) (Y axis)
Note that this is only a small part of the list of unstable isotopes. There are about 70
naturally occurring isotopes identified as unstable, and MANY more that are the result
of processes such as nuclear fission.
2. Plot the points that result from the table above, in the form (x,y), on your graph. Label each
point with the identity of the isotope that it represents. (2 points)
3. Complete the following:
a) For each isotope in the table above, identify a type of decay that could begin to
move the isotope toward the band of stability (1 point each)
b) Write a nuclear decay equation for each isotope undergoing the type of decay that
you have indicated. (1 point each)
4. Your work should be uploaded in canvas.
