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 a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
What is the half lie of a radioisotope?
The half-life of a radioisotope is the time it takes for half of the radioactive nuclei in a sample to decay. It is a characteristic property of each radioisotope and determines the rate at which the isotopes decay.
What does the half-life of a radioisotope refer to?
The length of time it takes for half of a radioactive sample to decay
What is the half life of radioisotope?
Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else. It's a characteristic of the isotope, for example, the half life of the isotope of iodine, I131 is 8.08 days. Half lives can vary from fractions of a second to thousands of years.
What is half life of a radioisotope if a g sample becomes g after 16 hours?
16 hours.
What is the half-life of a radioisotope if a g sample becomes g after 16 hours?
16 hours.
What is the half-life of a radioisotope if a 20-g sample becomes 10-g after 16 hours?
16 hours.
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.
What is a half-line of a radioisotope if a 50-g sample becomes 25g after 18 days?
A half-life of a radioisotope is the time required for half of a sample to decay. In this case, a 50-g sample becoming 25 g after 18 days indicates that the half-life of the radioisotope is 18 days, as the sample has decreased to half its original amount in that time.
What is the half of a radioisotope if a 100 g sample becomes 50 g after 20 years?
20
What is the half life of a radioisotope if a g sample becomes 5 g after 2 days?
1
What is the half life of a radioisotope if a 50 sample becomes 25 after 18 days?
18 days
What is the half life of a radioisotope if a 100g sample becomes 50 g after 20 years?
20 years (APEX)
What is the half life of a radioisotope if a 20g sample becomes 5g after 2 days?
The half-life of a radioisotope is the time it takes for half of a sample to decay. In this case, a 20g sample reduces to 5g after 2 days, indicating it has gone through two half-lives (20g to 10g in the first half-life, and 10g to 5g in the second). Therefore, each half-life is 1 day. Thus, the half-life of the radioisotope is 1 day.
What is the half life of a radioisotope if a 100g sample becomes 25g after 18 years?
The half-life of the radioisotope is 9 years. This is calculated by determining the time it took for half of the original sample to decay. Since the sample went from 100g to 25g in 18 years, it lost 75g in that time period. After the first half-life, the sample would have 50g remaining, and after the second half-life, it would have 25g remaining.
How much of a sample of radioisotope remains after one half-life?
One-half of the original amount. That's precisely the definition of "half-life".
