What type of atom are scientist looking for when they date a fossil and what is a half life?
They are looking for Carbon 14. Normal carbon is 12 but some carbon is an radioactive isotope called Carbon 14. Carbon 14 decays at a set rate. The amount left in artifacts that contain carbon can determine the age. Carbon-14 dating is a way of determining the found items up to about 50,000 years of age.
