WebPrecise dating has been accomplished since 1950. A chemical element consists of atoms with a specific number of protons in their nuclei but different atomic weights owing to variations in the number of neutrons. Atoms of the same element with differing atomic weights are called isotopes. WebOct 1, 2010 · Understanding the Basics. Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. But that’s not the case. The reason is simple. Carbon-14 can yield dates of only “thousands of years” before it all breaks down. The most well-known of all the radiometric dating methods is radiocarbon dating. http://www.most.org/wp-content/uploads/2016/04/Determining_Age_of_Rocks__Fossils.pdf size of a medium flat rate usps shipping box
