An atom "becomes" radioactive when it is created. It's that simple. Radioactivity is a phenomenon associated with atoms that have unstable nuclei. The key is that the protons and neutrons that form the nucleus "don't like" the "arrangement" there and the atomic nucleus is unstable. The "ratio" of protons to neutrons in a nucleus is intrinsically unstable. The instability is something that the nucleus, when it is formed (and by whatever means), has as an innate quality. It is unstable, and it isradioactive, and at some point in time, it will undergo decay, or even spontaneous fission, in the case of certain atoms, like uranium and plutonium.
What else can I help you with?
Do all atoms give out radiation?
No, not all atoms give off radiation. Only certain types of unstable atoms, known as radioactive atoms, undergo radioactive decay and emit radiation in the form of alpha particles, beta particles, or gamma rays.
Where do radioactive atoms start on the periodic table?
Radioactive atoms can be found throughout the periodic table. They can be naturally occurring elements like uranium and thorium, or they can be created synthetically in laboratories by bombarding stable atoms with particles.
Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?
yes
Is the best definition of half-life for a radioactive substance A. Half of the amount of time required for all of the radioactive atoms to decay. B. The amount of time required for half of the rad?
The best definition of half-life for a radioactive substance is B. The amount of time required for half of the radioactive atoms to decay. This concept describes the time it takes for a given quantity of a radioactive isotope to reduce to half its original amount through the process of radioactive decay. Option A is incorrect because it inaccurately suggests that half-life refers to the time for all atoms to decay, which is not the case.
What are the contributions of atoms in the field of medicine?
All medicines are made of atoms. Some treatments involve radioactive isotopes as do some diagnostic methods.
Are all atoms of actinides radioactive?
Yes. All of the actinides are radioactive.
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."
Atoms with certain characteristics are radioactive Which is least likely to be radioactive?
all atoms with an atomic number under 40
Do all atoms decay over time?
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
Do all atoms give out radiation?
No, not all atoms give off radiation. Only certain types of unstable atoms, known as radioactive atoms, undergo radioactive decay and emit radiation in the form of alpha particles, beta particles, or gamma rays.

Are radioactive atoms stable?
No
What planets and celestial bodies seem to be radioactive?
Stars seem to be, but they don't have big and/or unstable atoms such as most radioactive elements have. They release sub atomic units when their atoms fuse, along with rays such as gamma rays, which is why they can seem to be similar to other radioactive things. Some planets with atmostpheres that are ionised by ionising rays can also be similar to radioactive things perhaps.

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.
