Formula for carbon dating half life

A useful application of half-lives is radioactive dating.

This has to do with figuring out the age of ancient things.

The amount of carbon-14 in the atmosphere has not changed in thousands of years.

Even though it decays into nitrogen, new carbon-14 is always being formed when cosmic rays hit atoms high in the atmosphere.

The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.To answer this question, there is no need to solve for the radioactive decay equation.If 32 ÷ 8 = 4, then the material will go through 4 half-lives. What is the decay constant for a radioactive isotope with a half-life of 22.5 hours?If you could watch a single atom of a radioactive isotope, U-238, for example, you wouldn’t be able to predict when that particular atom might decay.It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.
