Half-life period for radioactive element is

A

Always constant

B

Variable

C

Independent of final concentrationn

D

Independent of initial concentration

Text Solution

Verified by Experts

The correct Answer is:
A, D
`t_(1//2) = (0.693)/(K)`
Therefore, `t_(1//2)` is always constant and independent of initial concentration.
