How long will it take half of a radioactive sample to decay?
NickBunting
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.

∙ 14y agoThis is known as the half-life of the isotope concerned.
Wiki User
∙ 13y agoThis is a samples half life and as it varies for each sample it depends on the element(s) you have
Wiki User
∙ 12y agoThe time it takes for one half of the atoms in a radioactive element to decay is called the element's half-life.

As a sample of a radioactive element decays its half-life?
No, the half life remains exactly the same throughout
What is radioactive half-life used for?
to determine how long it will take to half of nuclids to decay, having use in radioactive materials operations
What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).
What is the half lie of a radioisotope?
I assume you mean "half life". That means, how long does it take for half of the atoms in a sample to decay.
If the half-life of a radioactive substance is 10 hours how long will it take for 50 percent of it to decay?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.

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.

What does half-life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
What does the half life tell about a radioisotope?

What does the half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
What does a half life of a radioactive substance indicate?
It indicates how long it takes for the material to decay.
Why do scientist use radioactive dating?
To figure out how old something is based how long it takes elements in the sample to decay.

What do you mean by radio active half life?
In any radioactive substance, individual atoms will decay randomly. There is no way to know exactly when any particular atom will decay. On average and in broad terms, however, we can predict how many atoms will decay in any given period of time, and this time varies with the isotope involved. The "half-life" of a radioactive substance is the time that it will take for half of the atoms to decay. Very radioactive isotopes will decay quickly and will have very short half-lives; slightly radioactive isotopes will decay slowly and have long half-lives.
