What is the time required for half of a sample of radioactive isotope to break down?
This time is called "half life" and is specific for each isotope.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
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
The daughter isotope is 87.5 percent if the half-life of the isotope is 150 million years how old is the sample?
a sample is brought to the laboratory and the chemist determines the percentage of the daughter isotope is 87.5%. if the half-life of the isotope is 150 million years, how old is the sample?
When does Parent and daughter isotopes occur?
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
If the isotope have short half lives is that mean that the isotope is in a stable condition?
No. Only radioactive elements have half-lives, the half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size. Stable isotopes never 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.
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
What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
radioactive dating
. If the half-life of an unstable isotope is 10000 years and only 18 of the radioactive parent remains in a sample how old is the sample?
30,000
How long will it take half of a radioactive sample to decay?
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
