Neptunium-239 must undergo beta decay to generate plutonium-239.
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
No, not all elements decay over time. Some elements are stable and do not undergo radioactive decay.
If an isotope lies above the band of stability on a plot of neutrons vs protons, it will undergo beta decay.
Radioisotopes are unstable because they have an imbalance of protons and neutrons in their atomic nuclei. This imbalance causes them to be prone to undergo radioactive decay in order to achieve a more stable configuration.
There are over twenty known isotopes of argon. Of these all but three are radioactive and decay. Of naturally occurring argon, very nearly 100% is not radioactive, with only traces of one radioactive isotope found.
The two elements that undergo alpha decay are uranium and thorium.
radioactive 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.
When an isotope is stable, it does not undergo radioactive decay. Stable isotopes have a balanced number of protons and neutrons in the nucleus, which prevents them from spontaneously changing into another element over time.
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.
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
No, not all elements decay over time. Some elements are stable and do not undergo radioactive decay.
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.
