Carbon dating how stuff works
technology columnist David Pogue explores how isotopes of carbon can be used to determine the age of once-living matter. The difference between them is the number of neutrons in the nucleus.
Learn how variations in atomic structure form isotopes of an element and how the three natural isotopes of carbon differ from each other. Neutrons are electrically neutral particles that act as glue to hold atoms together. And that rare version of carbon has proven to be a crucial tool for unlocking the past.
Even many archaeologists don’t think “carbon dating” is completely accurate all the time.
It also linked to, and partially relied on, a website of dubious validity. So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock (e.g.rock that forms from lava from a volcanic eruption)—perhaps in the rock layers above where the fossil was found, or in the layers below.This information then has to be , based on certain beliefs.In fact, most fossils do not even contain radioactive minerals.
The University of Chicago professor developed radiocarbon dating in the late 1940s and won the 1960 Nobel Prize in chemistry for it.
