What is the famous isotope used in archeological dating?
carbon 12
I thought it was carbon 14
yes
carbon 14-- made an error
But if you knew, why are you asking these questions?
I need reaasurance, so when I have a test I know the exact answer
C-14 is ONE of the radioactive isotopes used for dating. U/Pb is another. K/Ar is another. I have never heard anything about C-14 being "famous." The particular isotope used depends upon the age of the object to be dated. For example, C-14 has a half-live of about 5700 years which is useful for determining the age of fossils that are not too old (in the thousands/ten thoushands of years); however, it isn't useful for determining the age of really old old stuff (say the earth) with an age of several billion years.
