How long does it take for half of the carbon-14 to convert back to nitrogen? Radioactive decay will cause carbon-14 to eventually become what? Why is carbon dating only useful for formerly living organisms?

The correct answer is -

- 5,730 Approximately

- carbon-12 isotopes

- carbon-14 decays at this steady rate

Explanation:

Half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years so the Carbon-14 has a half-life of 5,730 Approximately .

As Carbon-14 unstable it is considered a radioactive isotope of carbon, carbon-14 will inevitably decay back to carbon-12 isotopes.  

Radiocarbon dating is a method utilized by researchers to learn the ages of organic examples. It very well may be utilized on objects as old as around 62,000 years.  

Radiocarbon decays gradually in a living being, and the amount lost is ceaselessly renewed as long as the living being takes in air or food. Since carbon-14 decays at this steady rate, an estimate of the date at which an organism died can be made by estimating the measure of its residual radiocarbon.
