Problem: Determine whether or not the following nuclide is likely to be stable: Ne-25.

FREE Expert Solution

We’re being asked to determine if Ne-25 is stable.


Recall that the stability of an isotope depends on the ratio of neutrons to protons (N/Z). This means for stable isotopes with:

• Z ≤ 20; the N/Z ratio should be equal to 1.0

• 20 < Z ≤ 40; the N/Z ratio should be equal to 1.25

• 40 < Z ≤ 80; the N/Z ratio should be equal to 1.50

• Z < 83; the stable nuclide does not exist


The N/Z values for stable isotopes form the valley or band of stability:
