What is the half life of iodine-131 if after 24 days?
8 days
What is the half life in days of iodine-131?
eight days
What does a half life of 8 days mean?
What does it mean that the half life is 8 days. Simply it means that due to the decay half of the material will statistically decay every eight days. if you start with one kilo of iodine 131, eight days later you will have 1/2 kilo, in another 8 days you will have 1/4 kilo and in 8 more days 1/8 kilo, etc.
What percentage of an iodine-131 sample remains after 30 days?
What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%
What is the half-life of iodine-131 is after 32 days?
eight days
What is the half-life in days of iodine-131?
eight days
How long would it take for the iodine-131 sample to decay to 90% of the sample?
What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%
What is the half-life of iodine-131 if after 24 days?
8 days
What is the half-life of iodine-131 after 8 days?
1: The half-life of iodine-131 is eight days. Half of a given sample of iodine-131 decays after each eight-day time period elapses.
What percentage of iodine-131 remains after 32 days?
0.54
What is the decay rate of iodine-131?
8.04 days
What element has a half-life of 8 days?
iodine-131
Is there a half-life of 8 days?
As an example, iodine-131 is a radioisotope with a half-life of 8 days. It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131.
How many days is a half-life?
You know that the half-life of a radioactive nuclide, t1/2 , tells you the time needed for half of the atoms present in a sample to undergo radioactive decay. In this case, it takes 3.6 days for any sample of this substance to decay to half of its initial mass.
What does a half-life of one day mean?
half-life. [ hu0103fu2032lu012bfu2032 ] The average time needed for half the nuclei in a sample of a radioactive substance to undergo radioactive decay. The half-life of a substance does not equal half of its full duration of radioactivity.
What percentage of iodine-131 is left after 32 days?
0.54
How do I calculate half-life?
eight days
How fast does iodine-131 decay?
It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.
How long will it take for the substance to decay by 90% of its original amount?
about 997 years
How long will it take for three fourths of a sample of iodine-131 to decay?
0.54
What does a half-life of 8 days mean?
What does it mean that the half life is 8 days. Simply it means that due to the decay half of the material will statistically decay every eight days. if you start with one kilo of iodine 131, eight days later you will have 1/2 kilo, in another 8 days you will have 1/4 kilo and in 8 more days 1/8 kilo, etc.
How much of a 32 gram sample of I 131 remains after 48 days half-life of I 131 is 8 days?
eight days
What is the ½ life of iodine-131?
What percentage of an initial sample of 13153I remains after 30.0 days? We want the percentage of the original sample remaining after 30 days, or, in other words, we want the ratio N(30 days)/No. so the percentage remaining is 7.53%
