ReneTo perform Uranium-235 dating on a sample, you would measure the ratio of Uranium-235 to its decay product Lead-207 in the sample. By comparing this ratio to known rates of radioactive decay, you can determine the age of the sample. This method is commonly used for dating rocks and minerals that contain Uranium-235.

A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
How half life and carbon dating are related?
Carbon dating relies on the principle of half-life, which is the time it takes for half of a radioactive isotope to decay. In carbon dating, the radioactive isotope carbon-14 is used to determine the age of organic materials. By measuring the remaining amount of carbon-14 in a sample and knowing its half-life, scientists can calculate the age of the sample.
What is the problematic about the potassium argon method of radiometric dating?
Argon is a gas that may leak from a sample and provide inaccurate data
When did Willard Libby question the accuracy of radiocarbon dating it would be appreciated if the answer was in a quote?
Willard Libby first questioned the accuracy of radiocarbon dating in a 1963 interview with The New York Times, stating, "Radiocarbon dating is not a reliable measure of the true age of a sample."
How long does it take to get a result from carbon dating?
Carbon dating typically takes a few weeks to months to receive results, depending on the laboratory's workload and the sample's quality. The process involves extracting and analyzing carbon isotopes to determine the age of the sample.
