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.


What are radioactive atoms?

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.

How do radioisotopes of an element differ feom other isotopes?

Radioisotopes are "radioactive isotopes"; they are not stable. Radioactive atoms will decay, or break apart into other atoms, by emitting an electron, or a neutron or a positron or an alpha particle (2 protons and two neutrons). The rate at which this happens is measured by the "half-life"; after one half-life, half of the atoms will have decayed. After another half-life, half of the remaining atoms will have decayed. Atoms with short half-lives are highly radioactive, and can be fairly dangerous. Atoms with long half-lives are only slightly radioactive, and aren't all that dangerous.


Do radioactive atoms have different atomic weights than non radioactive atoms of the same element?

yes


Are radioactive atoms stable?

No


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 all atoms of actinides radioactive?

Yes. All of the actinides are radioactive.


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.


Can atoms of radioactive element change into atoms of another element by emitting radiation?

Yes


The way you express the time it takes for atoms in a radioactive substance to distintegrate is called?

The time used for dealing with nuclear decay is called a half life. Decay of a radioactive atom is something that happens by change, and the atoms of one isotope may be more or less prone to decay than the atoms of another. The way we normally express the rate of decay is to speak of the amount of time it takes for half of the atoms in a sample to decay, which is the same as the time during which any one atom of the sample has a 50% chance of decaying.


What happens to all radioactive isotopes?

All radioactive isotopes will disintegrate.
