The knowledge of half-life can be used to
- Create an element
-
Detect an element
- to combine elements
- Irradiate an element
The correct answer is: B
Explanation
Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive material to decrease by one-half
