# Carbon radioactive isotope dating

*03-Oct-2017 20:14*

Discover how scientists determine the age of fossils, rocks and other geologic phenomena by using the known half-lives of isotopes within each. These use radioactive minerals in rocks as geological.

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes . Radiometric dating is the determination of the date at which materials were formed by analyzing the decay of radioactive isotopes that were incorporated into the.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology, and even biomedicine.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.
