If the half-life of a radioactive substance is 10 hours how long will it take for 50 percent of it to decay?
The half-life of a radioactive isotope is defined as the time taken for the isotope to decay to half of its initial mass. So to decay to 50 percent of its initial mass will take one half-life of the isotope. One half-life of the isotope is 10 hours so the time taken to decay is also 10 hours.

Isotope A has half-life of seconds and isotope B has a half-life of millions of years which isotope is more radioactive?
Isotope A
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?

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 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 is radioactive?
When an isotope is unstable, it is said to be radioactive.
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.

How is radioactive decay used to determine the absolute age a rocks?
The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
When an isotope is blank it does not undergo radioactive decay?
when an isotope is it does not undergo radioactive decay
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 a radioisotope in chem?
Radioactive isotopes.
