How long will it take half of a radioactive sample to decay?
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
A sample of radioactive isotope has a halflife of 1 day how much of the original sample will be left at the end of the fourth day?
If a sample of radioactive material has a half-life of one week the original sample will have 50 percent of the original left at the end of the second week. The third week would be 25 percent of the sample. The fourth week would be 12.5 percent of the original sample.
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.
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.
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called?
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the half-life of the radioactive element. It is a characteristic property of each radioactive isotope and can vary greatly among different elements.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
How does the length of the half-life of the element correspond to the radioactivity of the element?
The length of time required for half of a sample of radioactive material to decay
Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
What if your cat is radioactive with the same halflife as carbon 14. how many years will it take for three fourths of your cat to degrade?
my grandma
Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.
How long will it take half of a radioactive sample to decay?
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What must be true for radioactive dating to be possible with a certain sample?
For radioactive dating to be possible, the sample must contain a measurable amount of a radioactive isotope with a known decay rate. The sample must be isolated from sources of contamination that could affect the accuracy of the dating. Additionally, the sample must have remained a closed system since the radioactive isotopes were incorporated, in order to accurately measure the decay products.
How do you calculate the activity of a radioactive sample?
The activity of a radioactive sample is calculated using the formula: Activity = λ*N, where λ is the decay constant of the isotope and N is the number of radioactive nuclei present in the sample. The unit of activity is becquerel (Bq).
What is the significance of a half life of a radioisotope?
It tells what fraction of a radioactive sample remains after a certain length of time.
The original sample of a radioactive substance?
Yes, and the question is ... ?
Does the size of a radioactive sample affect half-life?
No, the size of a radioactive sample does not affect its half-life. The half-life is a characteristic property of a radioactive isotope, defined as the time it takes for half of the radioactive atoms in a sample to decay. This property is intrinsic to the isotope itself and remains constant regardless of the amount of material present. Thus, whether you have a small or large sample, the half-life will remain the same.
