Formula for carbon 14 dating
After another 5,730 years, one-quarter of the original will remain.On the other hand, the time it will take a puddle to half-evaporate depends on how deep the puddle is.
In that case, it does not work to use the definition that states "half-life is the time required for exactly half of the entities to decay".
There are various simple exercises that demonstrate probabilistic decay, for example involving flipping coins or running a statistical computer program.
The decay of many physical quantities is not exponential—for example, the evaporation of water from a puddle, or (often) the chemical reaction of a molecule.
In other words, the probability of a radioactive atom decaying within its half-life is 50%.
For example, the image on the right is a simulation of many identical atoms undergoing radioactive decay.Carbon generally forms four covalent bonds with other atoms in larger molecules.
