A substance is the time required for half the atoms in a sample of a radioactive isotope to decay?
Half-life is the time required for half of the atoms in a sample of a radioactive isotope to decay. This concept is important in understanding the rate of decay of radioactive materials and is used in various fields such as nuclear physics and radiocarbon dating.
What is relative decay?
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
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
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.
What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
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
Is it true that The length of time required for half of the radioactive atoms in a sample to decay is its period?
No, the length of time required for half of the radioactive atoms in a sample to decay is its half-life, not period. The half-life is the amount of time it takes for half of the radioactive atoms in a sample to undergo radioactive decay. Period typically refers to the time it takes for a complete cycle of a repeating event.
