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 fraction of a radioactive sample decays after three half lives?
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.
What is the half-life of Tritium?
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.
After 6 half-lives What percentage of a radioactive sample remain?
After 6 half lives, the remaining will be (1/2)6 i.e 1/64 th of the initial amount. Hence by percentage it would be 1.5625 %
What fraction of a radioactive sample remains after one half-life?
Half of the original sample of a radio isotope remains after a half-life period. After two half-life periods, one-fourth of the radio isotope remains.
How much of 8-gram sample of Hydrogen-3 would still be present after 12.3 years if the half life of a H-3 is 12.3 years?
If 12.3 years is the half-life of Tritium (H-3), then @ 12.3 years only half of the tritium should remain or 4 grams.
What fraction of a sample remains after three half lives?
An eighth remains.
What percentage of a radioactive sample remains after 5 half-lives?
3.1 %
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotope?
One half life.
What is the half life tritium?
The half-life of tritium is 12.32 years (12 years 3 months and 26-ish days).
How many half-lives would be necessary for a sample of parent isotopes to decay to the point that only one-half of the sample is composed of parent isotopes?
One half life.
How much cesium is left after 4 half-lives?
1/16 of the original sample of any unstable element remains after 4 half lives.
A sample of a radioactive element has a mass of 80 g. How much parent and daughter materials are in the sample after two half-lives?
A half-life is the amount of time it takes for half of the material to decay. So if you started with 80g After 1 half-life you would have 40 g After 2 half-lives you would have 20 g After three half-lives you would have 10 g
How much of an 8 gram sample is left after 3 half lives?
2.66666666666667 grams
The half-life of an isotope is the time required for half the nuclei in a sample to?
Half-life is the length of time required for half the atoms in a radioactive sample to decay to some other type of atom. It is a logarithmic process, i.e. in one half-life, there is half the sample left, in two half-lives there is one quarter the sample left, in three half-lives there is one eight left, etc. The equation is... AT = A0 2 (-T/H) ... where A is activity, T is time, and H is half-life.
How many half-lives have elapsed to yield a sample with 125 atoms of C-14 and 375 atoms of N-14?
9 half lives have elapsed to yield a sample with 125 atoms of C-14 and 375 atoms of N-14.
