Balanced nuclear equation for carbon dating

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.

For example, say a fossil is found that has 35% carbon 14 compared to the living sample. We can use a formula for carbon 14 dating to find the answer.

When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.

Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death.

The negative sign indicates that N decreases with each decay event. Firstly, the exponential function is continuous, but the physical quantity N can only take positive integer values.

The solution to the above equation is N(t) = Nexp(-λt). Secondly, because it describes a random process, it is only statistically true.

So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.
