The length of time required for half of a sample of radioactive material to decay
How long it takes for half of a sample to decay to another form.
16 hours.
The isomer Ag-108m has a half life of 418(21) years.
the half life forms a type of clock used to calculate time passed
It tells how long it takes for a radioactive isotope to become a daughter element.
The half-life of the radioisotope Na-22 is 2.6 years.
It depends on the radioisotope. They do not all have the same half life.
The radioisotope with the shortest half-life among the following options is Polonium-214.
One-half of the original amount. That's precisely the definition of "half-life".
How long it takes for half of a sample to decay to another form.
16 hours.
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.
It is 432 years.
It is 7,380 years.
It is 15.02 hours.
It is 14.6 years.
It is 300,000 years.
