Solution: Radioactive dating is used to determine the date of ancient artifacts based on the charactersitics of the 14C isotope. The isotope is highly unstable and decays with a half-life of approximately 6000

Problem

Radioactive dating is used to determine the date of ancient artifacts based on the charactersitics of the 14C isotope. The isotope is highly unstable and decays with a half-life of approximately 6000 years. If archaeologists found an artifact from 18,000 years ago and there remains 1000 atoms of 14C, how many atoms were in the artifact when it was first formed?

a) 3375 atoms

b) 8000 atoms

c) 3000 atoms

d) 1000 atoms
