Question

Which of the following statements about the band of stability is correct?
A. It is a plot of beta emission compared to positron emission.
B. It is a plot of protons compared to neutrons for stable nuclei.
C. It is a plot of protons compared to neutrons for unstable nuclei.
D. Alpha emission occurs to the left of the band of stability.

Answer 1

this is what answers.com says

The band of stability is a way of viewing which isotopes of the elements are stable. If you make a graph of number of neutrons versus number of protons of the stable isotopes, you find that the stable isotopes make a thick curved line on the graph which is called the "band of stability." The lighter elements tend to have the number of neutrons equal to number of protons. The heavier elements tend to have more neutrons than protons. The band of stability can help you to predict the behavior of unstable radioactive isotopes as well, because you can predict which decay process will move the element closer to the "band of stability" so it will have the ideal ratio of neutrons to protons.
