Isotopes

Isotopes

•elements with the same number of protons but different numbers of neutrons.

•The average of mass numbers from all isotopes equals the Atomic Mass.

Carbon Dating

•Living organisms intake a small amount of C₁₄

•This intake stops upon death

•The half-life of C₁₄ is 5,730 years

•Therefore, a dead organism can be dated by the percentage of C₁₄ it contains
