What is a scientist who uses carbon-14 dating actually measuring?
In all cases the scientist is trying to measure the amount of radioactive decay of carbon-14 isotopes in order to establish the amount of time that has passed since the death of a living thing. As such all methods are based on establishing the remaining carbon-14 in a sample. However the specific type of carbon-14 dating being used will dictate how this is done.In the traditional approach the scientist is actually measuring the levels of beta activity from a sample. This is given off by the carbon-14 and so the amount of carbon-14 is established as the beta particles are used to identify the ratio of carbon-14 to its non-radioactive carbon-12.More modern methods use accelerator mass spectrometry and an atom counting approach to actually measure number of atoms of carbon-14 in a sample. This is generally more precise, although often significantly more costly, and both methods are still in use depending on the lab.
How do you write a story about an artifact?
The same way you write any other story -- plant your butt in a chair and get started! Make an outline listing everything you know about the artifact. Then, change each line into proper sentences and string them together into some sort of order -- any order that makes sense to you. There's your story. If you mean a fiction story, you'd already have the idea if you're meant to write that story. If you can't think of an idea, you don't really want to write the story. Here are some links.
Explain why radioactive decay must be constant in order for radiometric dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Why can't scientists use radiometric dating methods exclusively to date things?
Stratigraphy is used to determine the sequence of geological events by studying rock layers.There are six principles of stratigraphy: uniformitarianism, original horizontality, superposition, cross-cutting relationships, inclusions, and faunal succession.Relative age talks about what is older or younger than something else, while absolute age gives the actual age.There are several methods for finding the absolute age of something, including:Radiometric dating is used to find the absolute ages of rocks and fossils using the radioactive properties of elements (such as uranium) and their known half-lives. Uranium's half-life is 700 million years.Incremental dating provides year-to-year time frames by measuring the addition of new material to older material. Dendrochronology, the study of ice cores, and the study of varves are all types of incremental dating.Correlative dating involves mapping and comparing rocks and fossils in various areas to look for physical continuity, in order to draw conclusions on geologic trends and timeframes

What must be true in order to preform carbon-14 on an artifact?
Yes, it is possible: this science is called isotopic geochronology.
What are some benefits of carbon dating to humans?
Carbon dating is very important. Carbon dating is the radio-activity of Carbon 14 which is unstable so it emits protons once in a while in order to become a more stable isotope. Using Carbon dating, we can determine with accuracy how old something is.
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.
Why is radioactive dating unreliable in most situations?
Carbon dating in itself is not unreliable, it finds the approximate age of the carbon particles in a material. However, a piece of the material must be destroyed in order to date it.
What is a vendren?
It isa type of chemical that is mixed with the sulphate-oxide and carbon monoxide to order to perform an epxlosion.
What element do scientists use to compare the ratio of carbon-14 to in order to determine the age of the artifact?
The carbon 14 atom has a mind of its own and so it doesn't age so its 0 years old all the time because of the periodic table.
Why air is important to living thing?
Plants need carbon dioxide in order to perform photosynthesis which is how they make their food. Animals use oxygen to perform cellular respiration which converts the food we eat into energy. Both of these compounds (Carbon Dioxide and Oxygen) are found in air making it vital for them to perform these process.
Why is carbon-14 not useful to date rocks?
Although radiocarbon dating provides a useful tool there are some things that may make an artifact unsuitable for this process.The artifact is made from the wrong type of material.Carbon dating relies on measurement of radioactive decay from carbon 14 isotopes, some materials naturally do not contain enough carbon to date them.Radiocarbon dating is a destructive process. In order to conduct dating on an artifact you need a sample of it. Although this sample may only need to be very small, some artifacts are too precious to damage in this way.There may not be enough of it.Even if the sample is suitable in every other way, if you don't have enough of it then you cant do the test. Modern methods mean you may only need tiny amounts of carbon from the sample (0.1g) but depending on how much carbon is naturally in the material, this may translate to a fair amount of the original artifact. Carbon dates from small amounts of material also tend to be less accurate, and ideally you want to run several tests to be sure.The artifact may be too old. Radiocarbon dating is only effective back to a certain point. Beyond this there may not be enough radioactivity left in the sample to measure it. Also, radiocarbon dates need "correcting" on a calibration curve to correct the discrepancy between the age given in radiocarbon years and actual calendar years. Beyond around 45,000 years ago this curve is not so effective, and the remaining carbon-14 in the sample may be too small to measure.The artifact may be too young. Radiocarbon dating relies on the exchange of carbon through the carbon cycle. Recent human activity has affected the amounts of carbon in the atmosphere making carbon dating far less effective more recently than the early 1700. This is because processes such as the release old carbon into the atmosphere through the burning of fossil fuels and atmospheric nuclear weapons testing have led to dramatic peaks and dips in the amount of carbon 14 in the atmosphere.The sample may be contaminated.Contamination may occur before or after sampling and cause errors in the date that is produced. For example, water can disolve and deposit organic material changing the isotope levels. However, in most cases this can be dealt with in the lab during the sample preperation process. Archaeologists also take steps when selecting and recovering samples to minimise this potential problem.
What do chloroplast need to perform photosynthesis?
They need chlorophyll, carbon dioxide(CO2),
Why do some believe the carbon dating result in this case is flawed?
This question cannot be answered. In order of this question to be answered you will have to tell me which case you are talking about.
What nonmetals in the atmosphere and their combinations are essential to life on earth?
Oxygen, nitrogen, and yes, even carbon dioxide are essential to life on Earth (plants require carbon dioxide, in order to perform photosynthesis).
How does carbon dating or radioactive dating work and why is it used?
Everything has carbon in it. When the organism dies, it begins to disintegrate. We know the rate at which things disintegrate at, so we can determine how much carbon is left and then apply a scientific formula and figure out how old the organism is. Radioactive dating works much the same.
