Interpretation: The difference between radioisotopes from other isotopes is to be explained.
Concept Introduction: Atoms with the same number of protons and a different number of neutrons are called isotopes.

Answer to Problem 34A
Radioisotopes are unstable and isotopes are stable.
Explanation of Solution
Given Information: Radioisotopes are different from other isotopes.
A radioisotope is an unstable
Radioisotopes are unstable isotopes whereas isotopes can be categorized as both stable and unstable.
Radioisotopes can be found in nature for a short period of time whereas stable isotopes can be found in their elemental form.
Radioisotopes have half-lives whereas stable isotopes do not have half-lives.
While radioactive isotopes essentially experience radioactive decay, isotopes may or may not.
