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.

Scientists used radioactive decay to measure what?
amount if living organism that is expected to radioactive isotope.
Does carbon dating use nuclear fusion?
No, carbon dating does not use nuclear fusion. Carbon dating is a method used to determine the age of organic materials by measuring the remaining levels of a radioactive isotope called carbon-14. This process involves the decay of carbon-14, not nuclear fusion.
Compare and contrast two types of radioactive decay?
you have to know what radioactive decay is.
What is radiometer?
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.
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
constant half-life
What elements are used in radioactive dating?
don't know
What must be true for radioactive dating to be possible with a certain sample?
The sample must contain radioactive elements.
What types of elements are useful for dating materials?
Radioactive elements are used to date the age of rocks. Radioactive elements decay according to a known pattern. Scientists can use the elements of that pattern to determine when the rock with the original radioactive element was formed.
Scientists used radioactive decay to measure what?
amount if living organism that is expected to radioactive isotope.
What radioactive element is not commonly used in dating archaeological artefacts?
The most often used radioactive elements used in radiometric dating are carbon, potassium-argon and uranium-lead.Other elements are not, or very rarely used.
What is the process of abdsolut dating?
Absolute dating relies on radioactive decay of elements in a rock. When an igneous rock is formed it may contain elements that are a mixture.
Is a geological dating method based on the decay rates of radioactive elements?
Radio metric dating.
Is the dating method of determining the dates of old objects by using radioactive elements?
Radiometric
Determining the dates of old objects by using radioactive elements is called dating?
radiometric
Are all the radioactive elements found in the last group of the Periodic Table?
No, many other elements are radioactive or have radioactive isotopes. Examples of this are carbon 14, which is used in carbon dating, Radon, Krypton, Hydrogen, Iodine, and many others.
How do you carryout radiometric dating?
By the use of isotopes of radioactive elements through the determination of their half life.
What are the uses of each 5 radioactive elements?
- sources of energy - sources of penetrant radiations - smoke detectors - uses in medicine - uses as radioactive tracers - uses in radioactive dating of rocks
