Question

Expert Solution

Concept and Principle:

Most of the heavy nuclei will undergo decay to become stable by reducing the number of neutrons or protons. The rate at which unstable radioactive nuclei decay in a sample of material is called the activity of the sample.

The decay probability per nucleus per second is called the decay constant it is given by,

$λ = \frac{0.693}{t_{\frac{1}{2}}}$

Here t_1/2 is known as the half-life of the nucleus. It is the time that it takes for the activity to be reduced by half.
