As a sample of a radioactive element decays its half-life?
The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.
What is the half lie of a radioisotope?
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
How can you determine if an isotope is stable?
Isotopes are considered stable if they do not undergo radioactive decay. This can be determined by measuring the isotope's half-life, which is the time it takes for half of the atoms in a sample to decay. If the half-life is long, the isotope is considered stable.
What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.
Do radioactive isotopes disintegrate easily?
There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time.
How long does it take a radioactive atom to decay?
The time it takes for a radioactive atom to decay can vary significantly depending on the specific isotope. This is measured in terms of a half-life, which is the time it takes for half of the radioactive atoms in a sample to decay. Half-lives can range from fractions of a second to billions of years.

What does the half life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
How can you determine if an isotope is stable?
Isotopes are considered stable if they do not undergo radioactive decay. This can be determined by measuring the isotope's half-life, which is the time it takes for half of the atoms in a sample to decay. If the half-life is long, the isotope is considered stable.
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.
If a half life is 2000 years will a large amount of this radioactive sample be around for a long time?
Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.

How do you determine if an isotope is stable?
Isotopes are considered stable if they do not undergo radioactive decay over time. Scientists determine the stability of an isotope by measuring its half-life, which is the time it takes for half of the atoms in a sample to decay. If an isotope has a long half-life, it is considered stable.
How long will it take a 2kg sample of Thorium-219 to decay to 15.6g?
Thorium-219 has a half-life of about 1.4 minutes. To calculate the time it takes for a 2kg sample to decay to 15.6g, you would need to use the radioactive decay formula. This would involve determining the number of half-lives it takes for the 2kg sample to decay to 15.6g.
How long does it take for this radioactive material to decay through 2 half-lives?
It will take twice the half-life of the radioactive material for it to decay through two half-lives. If the half-life is 1 hour, it will take 2 hours for the material to decay through 2 half-lives.
Do radioactive isotopes disintegrate easily?
There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time.
