Note on half life equation

Introduction of half-life:

Today let me help you understand on half life equation. The time required for the atoms to disintegrate is considered as infinite. The half-life is considered for the radioactive element. Half-life of a radioactive element is the time required to reduce its size to the half of its initial amount of the radioactive sample. This half-life of radioactive is used for comparing the different radioactive elements and their activities.

Equation of Half-life:

Equation of half-life:

One of the characteristics of the radioactive element is half-life. It is the time taken to reduce its value half of the radioactive element. The equation of half-life is T/2. The range of half-life is from micro changes to billions of years. It is depends on the radioactive element.This could also help us on grams to liters.

Representation of equation of half-life:

Consider a radioactive element has N nuclei at initial. After first half-life time the radioactive element has N/2 nucleus and after next half-life time again it is reduced into N/4 and so on.
