A pure radioactive substance has a half-life of 3 hours. How long would it take a mass of 12g of that substance to decay to 3g?
Twice the half-life.
When the amount of a radioactive substance is reduced by 50 percent what has occurred?
Half-Life APEX (; xoxo
If 10 percent of a radioactive substance disintegrates in 4 days what is it's half-life?
20 days
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
What is the radioactive half-life of water?
Ordinary water is not radioactive, so it has no half-life.
What does a half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
To use radioactive dating for a substance you must know the substances?
Half-life
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
What is definition of half life?
The time required for half of the atoms in a radioactive substance to disintegrate.
A pure radioactive substance has a half-life of 3 hours. How long would it take a mass of 12g of that substance to decay to 3g?
Twice the half-life.
What is the half-life of a substance?
Half-life refers to a property of radioactive materials. The half life in the length of time it takes half of the quantity of an element to decay and become a more stable, non radioactive element. So if a 1 kg block of a substance had a half life of 10,000 years, in 10,000 years time there would 0.5 Kg of radioactive material remaining in the block. 10,000 years later there would again only be half as much, so there would then be 0.25 Kg of the radioactive material. Every further 10,000 years the quantity of the remaining radioactive material would half.
What are some other uses of half-life?
it is use for radioactive substance to determine its age of reaction.
When the amount of a radioactive substance is reduced by 50 percent what has occurred?
Half-Life APEX (; xoxo
What is the meaning of half life?
The term half-life refers to the period in which the radioactivity or number of atoms of a radioactive substance decreases by half. The term can be applied to any substance whose quantity decreases exponentially with time.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
How do you define half-life in pharmacology?
The term half-life refers to the period in which the radioactivity or number of atoms of a radioactive substance decreases by half. The term can be applied to any substance whose quantity decreases exponentially with time.
