A halflife usually describes the decay of discrete entities such as radioactive atoms in that case it does not work to use the definition that states halflife is the time required for exactly half of the entities to decay.

This is a list of radioactive isotopes ordered by halflife from shortest to longest.

Scientists look at halflife decay rates of radioactive isotopes to estimate when a particular atom might decay a useful application of halflives is radioactive datingthis has to do with figuring out the age of ancient things.

This lesson simulates radioactive decay to develop the understanding of what we mean by halflife.

Decay amp half life why is this chapter on halflife being presented the purpose of this chapter is to explain the process of radioactive decay and its relationship to the concept of halflife.

4 geological dating of igneous rocks certain elements with very long halflives can be used to date the geological age of igneous rocks and even the age of the earth has a halflife of 13 x 10 9 years it decays to form if the argon gas is trapped in the rock the ratio of potassium40 to argon40 decreases over time and the ratio can be used to.

The half life time is the amount of time it takes for half of the atoms in a sample to decay half life is a characteristic of each radioactive isotope.

Definition and formula halflife 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.
