14C has a half-life of

✅ Explanation: Carbon-14 (¹⁴C) is a radioactive isotope of carbon with a half-life of approximately 5730 years. This means that after 5730 years, half of the original amount of ¹⁴C in a sample will have decayed into nitrogen-14. This property makes ¹⁴C useful for radiocarbon dating, a technique used to determine the age of organic materials.
