Radioactive, as applied to an atom, means the nucleus is unstable, and "wants" to change into something else, either by emitting particles or energy. or by absorbing particles or energy.
Answ2. Radioactivity is a one-way street. It only loses total energy.
BUT it is possible to add energy/mass to a simple atom; as obviously happens in super nova by the process of fission.
This can also be done in an linear accelerator by accelerating a mass and firing it into a target.

What happens to atoms that are radioactive?
Radioactive atoms undergo spontaneous decay, emitting particles or energy in the form of radiation. This process transforms the atoms into different elements or isotopes, creating new elements that may also be radioactive. This decay continues until the atom reaches a stable state.
Do all atoms decay over time?
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
What is the characteristic time for the decay of a radioactive isotope?
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
How does half life work in the context of radioactive decay?
In the context of radioactive decay, half-life is the time it takes for half of the radioactive atoms in a sample to decay. This means that after one half-life, half of the original radioactive atoms have decayed, and after two half-lives, three-quarters have decayed, and so on. The concept of half-life helps scientists understand the rate of decay of radioactive substances.
Is the percentage of radioactive atoms that decay during one half-life always the same?
Yes, the percentage of radioactive atoms that decay during one half-life is always the same, which is 50%. This means that half of the radioactive atoms present will undergo radioactive decay within each half-life duration.
Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?
yes
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 radioactive atoms stable?
No
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
What happens to the numbers of radioactive and daughter atoms as the simulation proceeds?
As the simulation proceeds, the number of radioactive atoms decreases due to their decay into daughter atoms. Conversely, the number of daughter atoms increases as more radioactive atoms decay over time. This process continues until a stable ratio is reached, where the decay of parent atoms and the formation of daughter atoms balance out. Eventually, the count of radioactive atoms will approach zero while the number of daughter atoms may stabilize at a constant level.
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.
What radioactive element is the time it takes for half of the radioactive atoms to decay?
The half-life
Which atoms are least likely to be radioactive?
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
What happens to atoms that are radioactive?
Radioactive atoms undergo spontaneous decay, emitting particles or energy in the form of radiation. This process transforms the atoms into different elements or isotopes, creating new elements that may also be radioactive. This decay continues until the atom reaches a stable state.
Can atoms of radioactive element change into atoms of another element by emitting radiation?
Yes
What is a radioactive atoms?
Radioactive atoms are atoms that have unstable nuclei, which can undergo radioactive decay to become more stable. During this process, they emit radiation in the form of alpha particles, beta particles, or gamma rays. This emission of radiation can cause a change in the atom's composition or energy level.
What are atoms that emit particles and energy from their nuclei?
radioactive
