Question

Define decay constant and half life period and derive a realtion between them​

Answer 1

Answer:

decay constant proportionality between the side of population of radioactive atoms and the rate at which population decreases because of radioactive atoms. the relationship between the the half Life period and decay constant is T½=0.693|

Answer 2

Answer:

This shows that the population decays exponentially at a rate that depends on thedecay constant.

The time required for half of the original population of radioactive atoms to decay is called the half-life. 

The relationship between the half-life, T1/2,

and

the decay constant is given by T1/2 = 0.693/λ
