Chapter 5: Q. 67 (page 351)

Carbon-14 is a radioactive element with a half-life of about

5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14.

We are interested in the time (years) it takes to decay carbon-14. What is the decay rate (m)?

Short Answer

Expert verified

The value of decay rate is0.000121

Step by step solution

01

Definition of  decay rate 

Decay rate is indicated the rate of decreasing radioisotope of carbon-14. It defines the radioisotope exponentially reduces with the half life of 5370 years.

02

 The  process to measure decay rate  of carbon-14

The decay rate of carbon-14 is that is considered on the basis of the information decay rate of carbon-14.

The value of the decay rate mis 0.000121
