Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.So, if you were asked to find out carbon's half-life value (the time it takes to decrease to half of its original size), you'd solve for t number of years when in any remains will have broken down.So, objects older than that do not contain enough of the isotope to be dated.
The number of protons in the nucleus of an atom determines the element.This has caused many in the church to reevaluate the biblical creation account, specifically the meaning of the word “day” in Genesis 1.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years. Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay. A small amount of that carbon is in the form of a radioactive isotope called in the remains of an organism or artifact, plug that value into a generalized equation, and calculate the age of those remains.
The standards do not prescribe that students use or know with log identities, which form the basis for the "take the logarithm of both sides" approach.
