Generally, the smaller the nucleus, the less radioactive.

Atoms that are unstable are more likely to be what than atoms that are stable?

Atoms that are unstable are more likely to be radioactive than atoms that are stable. This means they can emit radiation in the form of alpha or beta particles, or gamma rays, in order to reach a more stable state.


What is likely to happen to atoms like plutonium with many neutrons and a heavy nucleus?

Radioactive disintegration or spontaneous fission


Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?

yes


Are radioactive atoms stable?

No


How do nuclear atoms differ from regular atoms?

All atoms are nuclear, in that they all have nuclei. Some atoms have unstable nuclei, making them radioactive. I'm afraid I have no idea what you mean by "nuclear atoms," unless you meant to say radioactive atoms, in which case the answer is "they have unstable nuclei and they're radioactive."


Are all atoms of actinides radioactive?

Yes. All of the actinides are radioactive.


Which atoms will always be radioactive?

There is no specific atom that will always be radioactive. Any atom with an unstable nucleus can be radioactive, resulting in the emission of radiation. Isotopes of certain elements, such as uranium and plutonium, are more likely to be radioactive due to their relatively large atomic numbers.


Do the numbers of radioactive and daughter atoms change at the same rate throughtout the simulation?

The numbers of radioactive and daughter atoms may or may not change at the same rate throughout simulation when compared to each other. Atoms generally start out at a higher rate of speed, and decrease to a lower one.


Isotopes with unstable nuclei are?

Isotopes with unstable nuclei are radioactive and can undergo radioactive decay to achieve a more stable state. This decay process involves the release of radiation such as alpha or beta particles. The unstable isotopes are often used in various applications, including medicine and energy production.
