Which isotope is used to date ancient artifacts such as fossils?

The main isotope used for determining the age of artifacts in Archaeology is carbon 14, however there are many others.
Other radiometric methods (methods based on the decay rates of radioactive isotopes) include:
- Potassium-Argon dating - Based on the decay of potassium 40
- Uranium Series dating - Based on the decay of several isotopes, including Uranium 238 (also used in fission track dating), Uranium 235, Thorium 230 and Protactinium 231.
- Lead 210 dating - Based (unsuprisingly) on the decay of Lead 210.
A climate based method, based on the "Oxygen Isotope timescale" can be used to broadly date things and uses ratios of Oxygen 18 to Oxygen 16.

What isotope is used to date ancient artifacts such as fossils?
Most commonly Carbon 14.
Which isotope is used to date ancient such as fossils?
The isotope of carbon is used to date the ancient fossils. Since every living creature had organic matter and carbon is an integral part of that organic matter, it is conventional to use carbon isotope.
How do scientists date fossils and artifacts?
Dating fossils and artifacts are easy. Scientist can look and tell how old the fossils by how many layers is under it.
Why radioactive decay to date fossils and artifacts?
Because they want to sound smarticles
How do scientists date the fossils and artifacts?
any other artifact or geological strata and compare it. Go to tables with similar artifacts.

How do archaeologists date fossils?
Scientists take samples of the carbon remaining in the fossil. They then use a form of carbon dating to determine its age. (it doesn't have to be a fossil, it could be any ancient remain, even a skull from fifty years ago, or a plate from the 1700's. Just wanted to clarify that a little bit more!)
What are the two ways to date a fossil?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
Radiocarbon is a type of?
Radiocarbon or Carbon-14 is an isotope of the element carbon. It is used extensively in archeology for dating artifacts. It can date carbon artifacts for upto 60,000 years. C-14 decays to non radioactive nitrogen-14 with half life of 5730 years.
What is a researcher who uses carbon dating on ancient item?
Archaeologists routinely use carbon dating on ancient artifacts in order to find an approximate date for them. Conservationist and Preservationists will also use carbon dating to find the date of objects they are working on.
What is two ways scientists can date fossils found in earth?
Stratigraphy, the relative positon of fossils in a sediment bed, is a common method. Assuming the beds lie in their natural position.Dating by using radioactive decay is another method used mainly for sub-fossil material such as archaeological artifacts; or for materials of geological age.
What kind of scientists study artifacts and ruins from past civilizations?
Archaeologists are the scientists who study artifacts and ruins from past civilizations. They analyze material remains, such as pottery, tools, and buildings, to understand ancient societies, their cultures, and their development over time. Archaeologists also use various techniques to date and interpret these artifacts to reconstruct the past.
