Carbon-14 is an example of an unstable isotope. It is widely used in radiocarbon dating to determine the age of ancient artifacts and fossils. Unlike stable isotopes, it decays over time, releasing radiation and transforming into a different element, nitrogen-14.

FAQs & Answers

  1. What makes an isotope unstable? An isotope is unstable when its nucleus has an imbalance of protons and neutrons, causing it to undergo radioactive decay to achieve a more stable state.
  2. How is carbon-14 used in radiocarbon dating? Carbon-14 decays over time at a known rate, allowing scientists to estimate the age of ancient organic materials by measuring the remaining carbon-14 content.
  3. What element does carbon-14 decay into? Carbon-14 decays into nitrogen-14 through the emission of radiation during radioactive decay.
