What is the half life of a radioisotope if a 100g sample becomes 50 g after 20 years?
20 years (APEX)
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 life of the Radioisotope H3?
The half-life of the radioisotope tritium (H-3) is about 12.32 years. This means that it takes approximately 12.32 years for half of a sample of tritium to decay into helium-3.
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 the Radioisotope Ba137?
The half-life of the radioisotope Ba-137 is approximately 11.23 minutes. This means that it takes 11.23 minutes for half of a sample of Ba-137 to decay into a more stable element.
What is the half of a radioisotope if a 100 g sample becomes 50 g after 20 years?

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.
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 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 g sample becomes 5 g after 2 days?

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 the Radioisotope H3?
The half-life of the radioisotope tritium (H-3) is about 12.32 years. This means that it takes approximately 12.32 years for half of a sample of tritium to decay into helium-3.
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 100 g sample 50 g after 20 years?
It would be 20 years. That is the length of time to lose one half the isotope.
What is the half life of a radioisotope if a 20 g sample becomes 10 g after 16 hours?
The half-life is 16 hours.
