If a radioactive material has a half-life of 10 years what fraction of the material will remain after 30 years?
One eighth would be left.
What was Bo Kimble's left handed free throw percentage?

What percentage of a restaurant bill should be left as a tip?

How do you change 4 into a percentage?
Move your decimal to places to the left which leaves you with 0.04 then convert that to a decimal: 4%.

How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.
What is the percentage of radioactive nuclei left after 3 half lives have passed?
12.5%
What is quadrupole nuclei?
See the Web Links to the left for the answer.
What is the longest radioactive halflife?
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).
Is the atom left after decay often radioactive?

How do groups on the periodic table compare?
Radioactive elements are in the groups (columns) to the left. On the right, there is non-radioactive metals, gases, and metalloids.
What happens after the radioactive half life has expired?
1/2 of what is left.
Suppose 128 radioactive atoms have a half-life of 15 seconds Approximately how many radioactive atoms will be left after 60 seconds?
8
How old is a fossil that has a radioactive material with a half life of 200 years if there is 25 percent of the original radioactive material left?
400 yrs
