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?
Its nucleus emits radioactive particles continuously.
An important force in radioactive atoms?
Weak Force
What is the difference between a simulation and actual radioactive decay?
Similarity: Both show that the radioactive atoms decrease and decayed atoms increase Difference: an actual decay is longer.
Decaying uranium atoms in the earths crust are what?
You can also say that they are radioactive.
What makes a nucleus radioactive?
If you are referring to a cell's nucleus than the simple answer is that's not radioactive. Radioactivity occurs when elemental atoms become unstable due to the loss or gain of additional neutrons; these unstable atoms are referred to as radioactive isotopes. If a cell's nucleus were radioactive it would not last very long, its structure and function would quickly degrade and collapse.
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
What must occur before a radioactive atoms ceases to undergo further radioactive decay?
A stable, nonradioactive atom must be formed.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
What happens to atoms that are radioactive?
Its nucleus emits radioactive particles continuously.
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
Which atoms are least likely to be radioactive?
Generally, the smaller the nucleus, the less radioactive.
Suppose 128 radioactive atoms have a half-life of 15 seconds Approximately how many radioactive atoms will be left after 60 seconds?
8
What radioactive element is the time it takes for half of the radioactive atoms to decay?
The half-life
Atoms that are unstable are more likely to be what than atoms that are stable?
radioisotopes
What is a radioactive atoms?
A radioactive atom is an atom that has an unstable nuclear force, and therefore either absorbs or emits a radioactive particle.
