2 hours ago Definition and Formula. Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value. The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not.

What is half life and how to calculate it?

To calculate the half-life of an element, go to the half-life tab:

  • Enter the initial and remaining quantity of the element in the corresponding input boxes.
  • Enter the total time it took to decay. You can select the unit of time from seconds, minutes, hours, months, year, etc.
  • Press the Calculate It will instantly show you the half-life of the element.

How to calculate half life?

The first step is to determine the number of half lives that have elapsed. number of half lives = 1 half life/6.13 hours x 1 day x 24 hours/day. number of half lives = 3.9 half lives. For each half life, the total amount of the isotope is reduced by half.

What is the formula for finding half life?

Half-Life Formula. It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t 1/2 = [R] 0 /2k; For a first-order reaction, the half-life is given by: t 1/2 = 0.693/k
