What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
Why After three half-lives what fraction of a radioactive sample remains?
After three half-lives, only 1/8 (or 12.5%) of the original radioactive sample remains. This is because each half-life reduces the amount of radioactive material by half, so after three half-lives, you would have (1/2) * (1/2) * (1/2) = 1/8 of the original sample remaining.
If half lives is 1 and time elasped is 1620 year what is mass remaining?
Half life has unit. That is unit of time. So it has to be mentioned. Let us assume that half life is 1 year. Okay. Now to know about the mass remaining we have to get the ratio (1/2)^1620. Hence remaining will be 1/(2^1620) * mass at the beginning
The half life of Rn-222 is 4 daysWhat was the original mass of a sample of this isotope remains after 21 hrs?
The half-life on 222Rn86 is 3.8235 days. A sample of this isotope will decay to 0.8533 of its original mass after 21 hours. AT = A0 2(-T/H) AT = (1) 2(-21/(24*3.8235)) AT = 0.8533
How long do atoms last in the context of nuclear decay and radioactive decay processes?
Atoms can last for varying amounts of time in the context of nuclear and radioactive decay processes. Some atoms can last for billions of years, while others may decay in a fraction of a second. The duration of an atom's existence depends on its specific properties and the type of decay it undergoes.
What fraction of a technetium radioisotope sample?
Please explain "sampke".
What is a remaining fraction?

A radioisotope has a half-life of 6.0 hours What fraction of the original mass will remain after 12.0 hours?
1/4
What is the significance of a half life of a radioisotope?
It tells what fraction of a radioactive sample remains after a certain length of time.
What fraction of the radioisotope remains in the body after one day?
If an isotope is absorbed into the body, the fraction that remains after one day depends on the radiological half-life of the isotope and the biological half-life (basically how fast the element can be eliminated from the body) of the element that the isotope represents.
What fraction of iodine 131 is remaining after 4 half- lives?
1/24 = 1/16
What is the refund fraction for a 55 month loan that is paid off with 15 months remaining?
343
How do you change fraction into a mixed fraction?
let say for example you have 7 fifths. There are 5 fifths in a whole. You still have two fifths remaining and therefore the fraction becomes 1 and 2 fifths (1 2/5).
If a radioactive material has half a life of 10 years what fraction of the material will remain after 30 years?
There will be 1/8 remaining.
What is 100 over 100 in simplest form and how?
1-the same numerator and denominator make it 1 whole without a fraction remaining
The first-order rate constant for the decay of the radioactive isotope tritium is 0.056 year-1 What fraction of the tritium initially in a sample is still present 50 years later?
To calculate the fraction of tritium remaining after 50 years, you would use the formula: fraction remaining = e^(-kt), where k is the rate constant and t is the time. Plugging in the values, you would find that the fraction of tritium remaining after 50 years is approximately 0.606 or 60.6%.
What is the half-lie of a radioisotope?
That would be "half-life". That means, how long does it take for half of the atoms in a sample to decay (convert into some other type of atom). Depending on the specific isotope, this "half-life" can be anything from a tiny fraction of a second, to billions of years.
