A substance is the time required for half the atoms in a sample of a radioactive isotope to decay?
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.
What does the half life of a radioisotope correspond to?
The length of time required for half of a sample of radioactive material to decay
As the temperature of a radioactive sample increases the rate of the nuclear decay?
It stays the same. Temperature has no effect on the rate of nuclear decay.
What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
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 long will it take for three-fourths of a sample of caesium-137 to decay?
It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
What do we call the time it takes for half of a radioactive sample to decay?
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.
Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
It's period of half of decay.
How long does it take a 100.00g sample of As-81 to decay to 6.25g?
132g
What does the half-life a radioisotope indicate?
The rate of decay for a radioactive sample
What does a half life of a radioisotope indicate?
The rate of decay for a radioactive sample
How were Alpha decay and beta decay discovered?
Alpha, beta, and gamma radiation were first observed from a sample of Radium in a magnetic field.
