Generally, the smaller the nucleus, the less 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.
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 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.
Radioisotopes.
It is not radioactive, under normal circumstances.
all atoms with an atomic number under 40
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.
Radioactive disintegration or spontaneous fission
yes
No
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."
Yes. All of the actinides are radioactive.

Helium, neon and argon are the least likely elements to form compounds.
