Want this question answered?
when an isotope is it does not undergo radioactive decay
The most common is alpha decay.
All isotopes of polonium can undergo alpha decay, a small number of isotopes can also undergo beta decay, K capture decay, or gamma decay.
No stable isotopes.

radioactive decay

No.
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.
No stable isotopes.
Americium-241 has an alpha decay associated with gamma.
As in all things, it will undergo decomposition and decay
No. Many atoms do not decay at all. Many that do undergo alpha decay. A few atoms emit neutron radiation.
Matter can be made to undergo nuclear decay in reactors, but it is a process that occurs spontaneously in nature.
