It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
when an isotope is it does not undergo radioactive decay
A stable, nonradioactive atom must be formed.
The most common is alpha decay.
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
There are 40 unstable isotopes (an element contained in xenon) that undergo radioactive decay.

Because it is an element francium cannot decompose. However, it does undergo nuclear decay, which is chemical terms, is different from decomposition.
The most common is alpha decay.
radioactive decay
Some isotypes are more stable than others. Decay occurs because of instability in isotopes, so stable isotopes do not undergo radioactive decay.
All elements have some isotopes that undergo radioactive decay, the question is how fast.Aluminum comes in three major isotopes, each with their own half-life:Al-26: 730000 years - 0% in natural aluminumAl-27: Stable - 100% in natural aluminumAl-28: 2.3 minutes - 0% in natural aluminumSo as natural aluminum is 100% Al-27 it does not undergo radioactive decay
234Th---- beta minus------234Pa
No. Only radioactive elements, which undergo radioactive decay can change to different elements.
