radiometric dating - Tulane University

The isotope 14 C, a radioactive form of carbon, is produced in the upper atmosphere by neutrons striking 14 N nuclei. The neutron is captured by the 14 N nucleus and knocks out a proton. Thus, we have a different element, 14 C. The isotope, 14C, is transported as 14 CO2, absorbed by plants, and eaten by animals.

Carbon dating is based upon the decay of 14 C, a radioactive. Problem 1- Calculate the amount of 14 C remaining in a sample. Problem 2- Calculate the.Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating.
