Half-life of a radioisotope is?
The half life of a radioisotope is the time taken for the number of radioactive atoms to decay to one-half. A free neutron has a half life of 10.6 minutes. The half life of carbon 11 is 20.3 minutes. Many isotopes have very short half lives, and many have very long ones.
What is radioisotope in a sentence?
radioisotope are very useful today. You can diagnose many things with them.
How many half-lives have passed?
To determine how many half-lives have passed, you would need to divide the total time passed by the half-life of the substance. The result would give you the number of half-lives that have occurred.
