How Carbon Dating WorksNuclear chemistry is the study of reactions that involve changes in nuclear structure. Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation:. Often a nuclide is referenced by the name of the element followed by a hyphen and the mass number. Protons and neutrons, collectively called nucleons , are packed together tightly in a nucleus. For example, water has a density of 1 gram per cubic centimeter, and iridium, one of the densest elements known, has a density of If this video looks familiar its because we also saw it back in Unit 2!

The technique they use, which is effective for dating objects no more than to years old with a high degree of accuracy, is called radiocarbon dating. Nuclear Chemistry | Crash Course Chemistry. | Grades 9- 13+.
In lieu of a glossary, technical terms are defined in sidebars next to the text. It's a superb primer on evolutionary theory, written for a general audience that conveys the science to the reader through examples of broad interest. The thoughtful writings about creationism, and teaching creationism in the classroom, are useful for everyone—scientist and nonscientist alike. For those who would like more in-depth discussion of any of the topics presented, an extensive resource list of publications and websites is included.

Any location in the ocean that is deeper than 10 metres has 14 C levels that can be up to years older than on the surface. This means is that when humans and animals whose diets are rich in seafood will have 14 C levels that provide older radiocarbon dates. Archaeologists take the marine reservoir effect into account by making small corrections to test results. When his skeleton was discovered inradiocarbon dating suggested it had been buried sometime between and However, other tests showed that the skeleton contained high levels of marine protein.
After taking the marine reservoir effect into account, radiocarbon dating actually pointed to a burial date between and These corrected results supported the theory that the skeleton belonged to Richard III.

Since it was first used at the end of the s, radiocarbon dating has remained one of the most important tools used by archaeologists. Although it is only one of many different dating methods, it is commonly used to determine the age of artifacts because most archaeological sites contain organic materials.
Radiocarbon dating can help understand technological advances, determine when a group of people moved to a certain region, or even identify a famous king.

I began my undergraduate degree at the University of British Columbia, specializing in the field of osteoarchaeology, or the study of human skeletal remains from archaeological sites. I completed my degree in at the University of Alberta, with a minor in First Nations studies, and have been working as an osteoarchaeologist ever since, first in Edmonton, AB, and most recently on the gorgeous Sunshine Coast of BC.
