Answer:
The longer the half-life, the more stable the nucleus is.
Explanation:
Well, you know that nuclear half-life represents the time needed for an initial sample of a radioactive substance to be halved. If this is the case, a long half-life would imply that it takes a very long time for the nuclide to decay to half of its initial mass. This of cource means that it is very stable.
