No, only artifacts that were once part of living things can be carbon dated. Thus a piece of carved ivory can be carbon dated, but a stone arrowhead cannot.

Can you give a sentence with carbon dating?
Carbon dating is a method of telling approximately how old an ancient object is. Here are some sentences.The scientists used carbon dating and decided that the mummy was 10,000 years old.Carbon dating is not perfect, but it can give you a rough idea.We studied carbon dating in class today.
How do scientists used carbon dating?
It involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. Carbon-14, or radiocarbon, is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
Why is radioactive decay is good method of measuring the absolute age of ancient fossils?
There are different types of atoms with the same chemical properties but with different numbers of neutrons in the atomic nucleus. These are called "isotopes". The most common element in most living organisms is carbon, which comes in two isotopes; carbon 12, which is normal ordinary carbon and carbon 14, which is very slightly radioactive. The radioactivity means that it will decay, changing into some other element, very slowly. The proportion of carbon 12 to carbon 14 is pretty steady, so as living things grow, they take in carbon 12 and carbon 14 in their food and air. When the plant or animal dies, they stop taking in new carbon. The carbon 12 remains the same, while the carbon 14 decays into something else very slowly. When we find the remains or the fossil of the dead animal or plant, we can measure how much carbon 12 and how much carbon 14 there is, and calculate how long it has been since the animal died.
Why is carbon dating important in history?
Carbon dating is the measuring of the proportion of carbon atoms which are of isotopic mass 14. These heavy isotopes of carbon decay into nitrogen, and the amount of time taken for half of them to decay is a fixed value, which archaeologists use to determine the age of a find.
What is radioisotope carbon dating?
Carbon 14 is the isotope that is used for carbon dating.
Is it true that archaeologists can estimate the age of any anicent artifact with carbon dating?
Yes, well, mostly anyway.
Can archaeologist estimate the age of a any ancient artifact with carbon dating?
Carbon dating can be used by archaeologists to estimate the age of artifacts that contain organic material. By measuring the decay of radioactive carbon isotopes in the artifact, scientists can calculate its age within a certain range. However, carbon dating is not always accurate for very old artifacts, and other dating methods may be used in conjunction with carbon dating for more precise results.
What is the radioactive property that archaeologists to help determine the age of ancient artifacts?
carbon 14
How old is an artifact that contains 12.5 percent of its original carbon-14?
The artifact is approximately 17,500 years old. This calculation is based on the half-life of carbon-14, which is about 5,730 years. By determining the percentage of remaining carbon-14 in the artifact, scientists can estimate its age.
How do you date an artifact?
To date an artifact, archaeologists use various methods such as radiocarbon dating, dendrochronology, pottery typology, stratigraphy, and seriation. These techniques help determine the age of the artifact based on its context, material composition, form, and associated finds. Combining multiple dating methods can provide a more accurate estimate of an artifact's age.
How is carbon 14 dating is used to determine the age of an artefact?
Carbon-14 dating is used to determine the age of organic artifacts by measuring the amount of radioactive carbon-14 present in the sample. By comparing the ratio of carbon-14 to carbon-12 in the artifact to the ratio in living organisms, scientists can estimate the age of the artifact based on the rate of carbon-14 decay.
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.
In order to perform carbon 14 dating on an artifact what must be true?
The artifact must contain carbon-14.
What type of radiometric dating do archeologists use to date an artifact that was once part of a living organism?
In most cases radiocarbon dating is the most commonly used method for dating an artifact made from a material which was once part of a living organism. However, there are other methods available. Although radiometric dating is a useful tool dendrochronology (also known as tree ring dating) remains the most effective and accurate method of dating certain species of wood (where a suitable sample can be found).
What are two scientific techniques that archaeologists use to gather more information about an artifact?
Archaeologists use radiocarbon dating to determine the age of organic artifacts by measuring the decay of radioactive carbon isotopes. Another technique is X-ray fluorescence (XRF) analysis, which helps identify the elemental composition of artifacts, providing insights into how objects were made and traded.
What must be true in order to preform carbon-14 on an artifact?
Yes, it is possible: this science is called isotopic geochronology.
What kinds of materials archaeologists use to study prehistory?
carbon 14
