The half-life period `t_(1//2)` of a radioactive element is N years. The period of its complete decays is

A

`N^2` years

B

2N years

C

`1/2 N^2` years

D

Infinity

Text Solution

Verified by Experts

The correct Answer is:
D
The `t_(1//2)` of a radioactive element = N years
`therefore` The period of its complete decay is infinity
