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.
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.
No, not all atoms decay over time. Some atoms are stable and do not undergo radioactive decay.
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.
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.
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.
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.
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.
The half-life
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.
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.
Yes
radioactive
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.
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.
