How are radioactive isotopes and their decay products used in radiometric dating?

It depends. Carbon 14 cannot be used to date rocks, but only matter of organic origin. We simply compare the ratio of carbon 14 to carbon 12, and ignore the decay product (N14). As the half life of carbon 14 is 5730 years, we can (with the older equipment) fairly reliably date organic material back about 10 half lives, or pretty close to 60,000 years.
Uranium/uranium, uranium/thorium, and potassium/argon are three sets of long lived isotopes that are often found together, and work quite well for dating ash and rock of volcanic origin.

Radiometric dating is possible because the rates of decay of radioactive isotopes .?
Are constant
What knowledge is radiometric dating based upon?
radiometric dating is base on the half life of the radioactive atoms
Can use radiometric dating on all minerals to tell their absolute age?
No, radiometric dating can only be used on certain minerals that contain radioactive isotopes. These minerals include zircon, potassium feldspar, and biotite, among others. Not all minerals contain radioactive isotopes, so radiometric dating cannot be applied to all minerals.
How does radioactive decay and radiometric dating differ?
Archaeology
Scientists use the amount of radioactive isotopes found in rocks and fossils to calculate their ages this process is called?
the rock and the fossils are made out of lava stuff
Radiometric dating is possible because the rates of decay of radioactive isotopes .?
Are constant
Radiometric dating is possible because the rates of decay of radioactive isotopes?
Radiometric dating is possible because the rates of decay of radioactive isotopes are constant and predictable over time. By measuring the amount of remaining parent and daughter isotopes in a sample, scientists can determine the age of the sample.
What knowledge is radiometric dating based upon?
radiometric dating is base on the half life of the radioactive atoms
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 disappear before any useful period of time passed.
How do you carryout radiometric dating?
By the use of isotopes of radioactive elements through the determination of their half life.
Can use radiometric dating on all minerals to tell their absolute age?
No, radiometric dating can only be used on certain minerals that contain radioactive isotopes. These minerals include zircon, potassium feldspar, and biotite, among others. Not all minerals contain radioactive isotopes, so radiometric dating cannot be applied to all minerals.
What is radiometeic dating?
Radiometric dating is a technique that detects the presence and abundance of radioactive isotopes and is used to give approximate ages of materials. One common form is carbon dating.

How does radioactive decay and radiometric dating differ?
Archaeology
What isotopes is most useful for dating plant and animal remains?
CARBON DATING The most common fossil dating techniques are radiometric dating techniques. Radiometric dating uses knowledge of the decay rates of unstable ( radioactive ) nuclei to determine, by comparison with the proportion of stable nuclei in a fossil sample, the date of the introduction of the radioactive material into the live organism, especially if the isotope was ingested while the organism was alive.
Is a geological dating method based on the decay rates of radioactive elements?
Radio metric dating.
How is radioactive decay used to date rocks?
Radioactive decay is used to date rocks by measuring the amount of parent and daughter isotopes in a sample. The rate of decay of a radioactive isotope is constant, allowing scientists to calculate the age of a rock by comparing the ratios of parent and daughter isotopes present. This technique is known as radiometric dating and can be used to determine the age of rocks millions to billions of years old.
