How long will it take half of a radioactive sample to decay?
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
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.
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
constant half-life
Which of these four radioactive elements would you choose to date a fossil from the most recent epoch?
Four elements are not mentioned but fossils contain organic material that means carbon compounds so carbon-13 isotope is more suitable, in case of radioactive elements that isotope is most suitable which have the half life period in millions of years.
What does it mean if an element it radioactive?
this is because an element is sometimes never radioactive but one may be made just to be radioactive this is because an element is sometimes never radioactive but one may be made just to be radioactive
Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.
Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
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 time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
How is a radioactive isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.
When an isotope is blank it is radioactive?
When an isotope is unstable, it is said to be radioactive.
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
That's called a daughter isotope, or a daughter product. (The original isotope that decayed is the parent isotope.)
When an isotope is blank it does not undergo radioactive decay?
when an isotope is it does not undergo radioactive decay
What is the half life of an isotope?
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
What is the process in which one isotope changes to another isotope?
Radioactive decay is the process in which one isotope is changed into another isotope.
