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.

∙ 11y agoCarbon dating is radiometric dating, using the carbon 14 isotope. Carbon 14 is used for fossils of fairly recent origin, as it becomes less and less accurate beyond 10 half lives (about 50 thousand years). One half-life of carbon 14 is about 5370 years.
Longer lived isotopes such as uranium/uranium, uranium/thorium, and potassium/argon are used to date inorganic materials of volcanic origin, such as rock or layers of volcanic ash, and can yield results ranging from millions to billions of years, accurate to within about a hundred thousand years.

∙ 10y agoRelative age dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object or date of an event.
Both relative dating and absolute dating are complimentary tools tools used to assign temporal characteristics to a sequence of events. Both are attempting to get information on the history of events.
Tools like radiometric dating use radioactive isotopes and known decay rates and this allows some samples to be assigned a certain age to within some accuracy. Assigning a certain age or date is a form of absolute dating.
The primary difference is that absolute dating assigns an actual time or age to an event or object. Relative dating simply says one is older than the other but no age is specified.

How does carbon dating work if the half life is 0?
It isn't 0Carbon dating uses the radioactive isotope Carbon-14 which has a half life of 5730 years. It may be used to date organic materials up to roughly 40,000 years old.BTW, ordinary nonradioactive carbon (Carbon-12 and Carbon-13) by definition have a half life of infinity (not 0), as they do not decay!
Would carbon dating work if carbon-14 atoms did not decay at a constant rate and why?
Statistically carbon-14 atoms decay at a constant rate.
What kind of dating do you do in the lab?
For example, radioactive dating.Also, two people who work in a lab (typically a man and a woman) could have a date.
Why does carbon-14 dating only work for objects that are less than 50000 years old?
After a certain number of half-lives elapses, the remaining amount of carbon-14 is too low to measure with precision. Also, the risk of contamination becomes much greater; i.e., a small contamination will have a larger effect.
Who is keishia coles dating?
keyshia cole isn't dating because she was in a long-term relationship and it did not work out
How does carbon dating work ma?
This method of dating is based on the radioactive decay of carbon-14.

What type of dating involves the use of radioactive elements and half-lives?
Radioactive decay may be used in carbon dating, testing for the amounts of a radioactive carbon isotope (C14) in the remains of some organism. C14 obviously only works on organic material which was once alive, such as wood or bone. Because C14 has a very short half life, less than 6000 years, it does not work on material much over 60,000 years (about ten half lives). Potassium/Argon is another useful set of isotopes that can yield the ages of rocks and inorganic matter far older--many millions of years old.
What type of rock does radioactive dating work with?
Rocks in general are not dated, but a fossil would be.
What type of rock does radioactive dating work best with?
Rocks in general are not dated, but a fossil would be.
What is a dating method used to estimate Ages after something dies?
For things that were once living the best method is what is called Carbon Dating, which is based on the decay of carbon-14. As long as the thing remains alive it is in equilibrium with the environment and maintains a constant level of carbon-14 in its tissues. On death this equilibrium is broken and the remaining carbon-14 slowly decays away without anymore replacing it from the environment. The age can be calculated by measuring how much carbon-14 has been lost from the equilibrium level.The problems with Carbon Dating is that it does not work for things that died more than 40,000 years ago due to the fact that the halflife of carbon-14 is 5570 years so after 40,000 years there isn't enough left to measure, and the environmental level of carbon-14 does change some over time so known reference sources (e.g. tree rings) must be used for recalibration of Carbon Dating results.Beyond 40,000 years other radiometric dating methods must be used, but unlike Carbon Dating they cannot determine age from death.
How is radioactive decay useful in dating rocks and minerals?
Radioactive decay has a constant rate of change, therefore it con be used to somewhat accurately tell the age of an object if you work backwards through the use of half-lifes (half of the existing radioactive material decays, leaving half of the original in its original form)

What radioactive technique is used to determine the age of fossils?
What radioactive technique is used to determine the age of fossils? The radioactive technique of radiometric dating is used to determine the age of fossils. This is a way to measure the proportions of a daughter isotope and the parent radioisotope of some element trapped inside a rock since the time the rock formed. A radioisotope is a form of an element with an unstable nucleus. Radioactive atoms decay, or lose energy and subatomic particles until they reach a more stable form. It is not possible to predict the exact instant of one atom's decay, but a predictable number of an isotope's atoms will decay over a period of time. Like the ticking of a perfect clock, the characteristic rate of decay for each isotope is constant. In other words, changes in pressure, temperature, or chemical state do not alter it. Radiometric dating doesn't work for sedimentary rock. It works for volcanic rock or ashes, which hold the most fossils. The ratio of carbon 14 to carbon 12 is used to date recent fossils that still contain some carbon. The only way to date older fossils is to determine their position relative to any volcanic rocks in the same area. This dating method has an error factor of less than 10 percent.
