Age of fossil may be found out by determining the ratio of two isotopes of carbon. The isotopes are1 point(a) C-12 and C-13(b) C-13 and C-14(c) C-12 and C-14(d) C-12 and carbon black

In the process of radiometric dating, if the percent of the original amount of carbon-14 present in a fossil is 12.5%, how old is the fossil? The half-life of carbon-14 is 5,730 years.Multiple choice question.11,460 years old17,190 years old5,700 years old22,920 years old

The carbon-14 in the fossil had five half-lives. The fossil was between 18,000 and 21,000 years old.The amount of carbon-14 in the fossil decreased over time.The fossil was older than other fossils found in the same area

If a fossil was found that had 50% radioactive carbon-14 and 50% decayed element, approximately how old is the fossil?

When an organism dies, the intake of carbon atoms stops, and as the radioactive isotope carbon-14 decays over time into the more stable atom ______, the amount of the remaining ______ can be used to estimate the age of a fossil.Multiple choice question.carbon-12; carbon-14carbon-12; carbon-12
