Question

Plutonium has a decay constant of 2.75 × 10-16 s-1. Suppose we had a 1.00 g sample what will be its activity?

Expert Solution

Concept and Principle:

Radioactive decay is the process by which unstable nuclei spontaneously lose energy to become stable. This process will alter the Z and N value till the element becomes stable.

The rate at which this decay takes place in a given sample of radioactive material is called activity.

It is given by,

$a = N λ$

Here N is the number of radioactive nuclei and λ is the decay constant.
