Answer 2

Answer:

0

Explanation:

As a stable nuclei will never decay at all so time taken to fall to 1/e of its initial value will be ∞ whose inverse is zero.

So decay constant for stable nuclei is:

Decay constant λ=1/∞=0

Hence, the decay constant for the stable end product of the series will be zero.

So, the correct answer is option D.

Note- This constant of decline also called constant likelihood will vary considerably between various types of nuclei, contributing to the very different rates of decline observed. In time, the radioactive decay of any number of atoms (mass) is exponential. The decay rate is completely different from temperature. Many studies have shown that alpha and beta declines have not been influenced by environmental influences such as temperature, air pressure or organic content.
