What is the formula linking number of nuclei of undecayed nuclei (N), initial number of undecayed nuclei (N0), decay constant (λ\lambda), and time (t)

N = N0eλt


N = number of undecayed nuclei

N0 = initial number of undecayed nuclei

λ\lambda = decay constant (s-1)

t = time (s)

What is carbon dating?

Carbon dating is a method used to determine the age of organic material by measuring the radioactivity of its carbon-14 content.

How is the age of an object estimated using carbon dating?

The age is estimated by measuring the amount of carbon-14 in the sample and comparing it to the expected initial amount.

What is the limitation of carbon dating?

Carbon dating is less accurate for materials older than about 50,000 years, as the amount of carbon-14 left becomes too small to measure accurately.
