What is the difference between and radioactive and stable isotope?

Answer 1

Radioactive isotopes emit radiation in the form of alpha, beta, positron or gamma rays to become a stable isotope of any given particular element. This is caused by the instability of the nucleus of the atom. The stabilising process in which unstable atoms undergo is known as radioactive decay.

Isotopes that are stable do not emit radiation. For example; Carbon-12 is stable and carbon-14 is radioactive.

Answer 4

A stable isotope will not decay. A radioactive isotope is expected to decay over time and the term "half-life" describes the time period in which it will happen. Given a mole of radioactive atoms, half will have decayed in the half-life, then a half of the remaining will decay in the next half-life period, and so on. There is no predicting for any particular atom, we must simply treat it as a matter of probability.

Answer 5

The radioactive isotope is unstable and is desintegrated in time.
