The most useful isotope is uranium 235 which occurs naturally as 0.7 percent uranium as found. Plutonium 239 is also useful but has to be made in a reactor from uranium 238

And uranium, thorium and plutonium isotopes are used as nuclear fuels in nuclear reactors.

How might you use a radioactive isotope to find out whether the oxygen in carbon dioxide comes from sugar or oxygen gas?
Radiolabel the sugar oxygens, then carry out the reaction and see if the carbon dioxide that's released is radioactive or not. Alternatively, you could use radioactive oxygen gas.
What does carbordating mean?
Do you mean carbon dating? Carbon dating is a process that scientists use to try to ascertain the age of an item by analyzing the amount of a radioactive carbon isotope that is present in the item. Generally this is used to date biological items. Like, really old trees and stuff. The percent of the radioactive isotope in the specimen is accumulated to normal levels as the thing was alive, after it is dead it stops absorbing new carbon and thus by measuring the ratio of isotopes that are decaying we can determine the age of the item. (using the half-life of the radioactive isotope)
Compared to 31P the radioactive isotope 32P has?
32 Phosphorus has 1 extra neutron. It's a really cool radionuclide to since scientists use it to radiolabel lots of small molecules.
How do you use Radioactive dating in a sentence?
My nerdy brother wants to start a radioactive dating website! The use of radiometric, or radioactive, dating was initiated in 1907 by Bertram Boltwood.
How do you use radioactive element in a sentence?
A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.
What is one radioactive isotope the geologists can use to learn the exact age of the rock?
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
What is one radioactive isotope the geologist can use to learn exact age of the rock?
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
When a radioactive tracer is used why is it best to use a radioactive isotope that decays into a stable isotope?
The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling.
Why is curium 242 not suitable for use in smoke detectors?
It is radioactive. ------------------------------- Incorrect answer: americium-241, the usual isotope in smoke detectors is more radioactive.
What is the similarity of radioactive isotope and radioactive dating?
Radioactive isotopes are used for radioactive dating. For example, you would use radioactive isotope Carbon-14 to date anything under 70,000 years that was once living. Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances). The rate at which a parent isotope decays to its daughter isotope is considered one half life. Carbon-14 has a half life of 5730 years and its daughter isotope is Nitrogen-14. In order to determine how old something is you have to find out how much of the parent isotope is present in relation to the daughter.
Can scientist use the isotope c-14 to date granite?
Yes because they look at the ammount of radioactive decay and they can determine the age of the granite. As the radioactive isotope decreases the non radioactive element increases. The less radioactive decay ammount there is the older it is.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
What is the use of measuring the activity of a radioactive isotope in a sample to determine its age?
radioactive dating
Will iodine ever under go nuclear reaction?
If you use a heavier isotope of iodine, it should be radioactive.
What radioactive isotope did hershey and chase use to tag phage DNA?
phosphorus - 32P
State an industrial use of a radioactive isotope?
Radioactive isotopes are used to test wear and tear inside a car engine.Radioactive isotopes are used in detecting and preventing the corrosion of metals.
How might you use a radioactive isotope to find out whether the oxygen in carbon dioxide comes from sugar or oxygen gas?
Radiolabel the sugar oxygens, then carry out the reaction and see if the carbon dioxide that's released is radioactive or not. Alternatively, you could use radioactive oxygen gas.
