A substance is the time required for half the atoms in a sample of a radioactive isotope to decay?
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.
As a sample of a radioactive element decays its half-life?
The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.
What part of a radioactive sample remains unchanged after 2 half lives?
After 2 half lives, 25% of the original radioactive sample remains unchanged. This is because half of the sample decays in each half life, so after 1 half life, 50% has decayed, and after 2 half lives, another 50% has decayed, leaving 25% unchanged.
What is the half-life of a radioisotope if a 40g sample becomes 10g after 20 minutes'?
The half-life of the radioisotope is 20 minutes. This means that in 20 minutes, half of the original sample (20g) remains. Therefore, if a 40g sample becomes 10g after 20 minutes, it has undergone 1 half-life.
How much of the original sample will be left at the end of the second day if a sample of radioactive isotope has a half life of 1 day?
Hi, Each half-life means the mass of the sample has decreased by 1/2 its mass. Thus; After 1 half-life, 1/2 the sample has decayed. After 2 half-lives 3/4 of the sample has decayed. Hope this helps.
How does halving a sample affect the weight of the sample?
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
What happens to the mass of a sample containing a radioactive element during its half-life?
Chawad says... They are directly proportional
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 happens to the count rate from a radioactive sample during 3 half lives?
The count rate decreases to 12.5% of the initial value after 3 half-lives, as radioactivity is reduced by half during each half-life.

What percentage of a radioactive sample remains after 5 half-lives?
After 5 half-lives, 3.125% (or 1/2^5) of a radioactive sample remains. Each half-life reduces the sample by half, so after 5 half-lives, there is only a small fraction of the original sample remaining.
Is the the book Sea Of Monsters good?
Yes,Percy Jackson gets the golden fleece he gets a cyclops as a half brother and at the ending a miracle happens
What happens if we sample the signal at sampling frequency nearer to signal frequency?
If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.
Half of what gets you 9 in a half?
Half of 19 gets you 9 in a half 9.5
What happens when your car gets broken in two?
it is broken and somebody needs to fix it fast and it is also cut in half
What happens when you give a Pokemon a revive?
that Pokemon gets half of his HP back What ever Pokemon you give it to, ittle bring them back alive with half HP
What do we call the time it takes for half of a radioactive sample to decay?
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.
