Question

A element source has a decayed constant of 13.6pico per second. Calculate the half life of this element. ​

Answer 1

5.1 x 10¹⁰s

Step-by-step explanation:

Given parameters:

Decay constant = 13.6 x 10⁻¹²/s

Unknown:

Half life of the element = ?

Solution:

From the decay constant, we can find the half-life of this radioactive element.

Half-life =
`(0.693)/(decay constant)`

Half-life =
`(0.693)/(13.6 x 10^(-12) )` = 5.1 x 10¹⁰s
