The stable end product is a nonradioactive isotope of another element, e. To work out what element a radioisotope will transform into you can use something called a Segre chart. Radioactive dating is is used to determine the age of once-lived organic matter plant, animal, human etc. Perhaps the best known example of this technique, radiocarbon dating, examines how much carbon radioisotope remains within an organism in comparison with the stable carbon nonradioactive isotope.
A radioactive isotope is a thing an unstable atom , radioactive dating is something you do with that thing using the ratio of parent to daughter element to determine age.

What do radioactive isotopes decay into? It depends on which isotope. Please restate the question, and be specific as to which isotope you are interested in. Do radioactive isotopes disintegrate easily? There is a very wide range of half-life for different radioactive isotopes, ranging from the billions of years to very small fractions of a second. So some isotopes disintegrate immediately, and others last a very long time. How is a radioactive isotope used to date a sample rock? The half-life of all common radio-isotopes for all elements is well-known.
The decay of selected elements in a substance most commonly used is carbon gives a good estimate of the sample's age, say to within two to five thousand years. When estimating the age of a rock sample that may be 4 billion … years old, that is excellent accuracy. MORE What are the 2 radioactive isotopes? There are a lot more than 2 radio active isotopes To answer this question a naturally or created radioactive element needs to be mentioned.
What is the order of reaction of radioactive isotope?

I believe it is a first order reaction. So the integrated rate law would be: Radioactive isotopes undergo what is known as radioactive decay not to be confused with the organic decay that rotting food would undergo. A decaying isotope emits radiation, and is transmuted into a different isotope.
Uranium eventually becomes lead. How does the half life of a radioactive isotope affect the usefulness of that isotope in radioactive dating? The half-life of an isotope is only useful in dating if the half-life is a reasonable fraction of the actual age.

For example, a half-life in the range of days or even a few years is meaningless if the sample is several thousand years old. On the other hand, a half-life in the hundreds of thousands … of years is also not useful if the sample is, say, 15, years old. All of this has to do with statistical validity of the measurement of the ratio remaining. That brings me to the second factor. Half-life is only meaningful if you have something to compare it to. You need to be able to correlate the measurement of the sample against some reference point.
Since quantity of the sample is a function of both half-life intervals age and original quantity, attempting to measure the age without the original quantity will fail. The most commonly used method, carbon dating, solves this problem by comparing the quantity of carbon against carbon and carbon, both of which are stable. This works for carbon dating because the ratio is relatively constant when the biochemical composition of the sample represents an "alive" sample.
Carbon dating depends on plant material that is associated or attached to the sample. We call this carbonaceous material.

When the plant material "dies", the constant refreshing of the ratio stops. This allows us to date a sample within a short region of time that is not an excessively long number of carbon half-lives. Scientists calibrate the ratio using independent samples of materials that are dated by other means.
MORE If an element has isotopes does it mean they are radioactive? No, many elements have several isotopes that are not radioactive.

Iodine is used to image the brain. Cobalt is commonly used to irradiate cancer cells in the hope of killing or shrinking tumors.

Sodium is used to trace the flow of blood … and detect possible constrictions or obstructions in the circulatory system. Carbon is used to trace the path of carbon in photosynthesis. MORE What happens to a radioactive isotope as it decays? It depends on the radioactive decay mode. If it emits gamma rays, it transforms into same element but in a more stable state. If it emits n … eutron, it transforms into more stable isotope.
If it emits alpha or beta particle, it transforms into another element that is more stable. MORE What is the half life of radioactive isotope? The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start ofthe period to a different isotope, usually an isotope of adifferent element. This period of time is different for differentisotopes, with known isotope half lives ranging from … femtosecondsto many billions of years. MORE Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappearbefore any useful period of time passed. How do an isotopes and a radioactive isotopes ifferent? Simply by being radioactive or not. An isotope is an atomic variantof the same element, and has the same chemical characteristics, butis not necessarily radioactive.
