Correlating radioisotope dating methods

Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age.Other methods such as Potassium-argon dating and Isochron dating are based on faulty assumptions and so unreliable as to be useless.

One year later Boltwood (1907) developed the chemical U-Pb method. By combining Von Weizsackers argon abundance arguments with Kohlhorsters observation that potassium emitted gamma-radiation, Bramley (1937) presented strong evidence that potassium underwent dual decay.was published, the earth was "scientifically" determined to be 100 million years old. In 1947, science firmly established that the earth was 3.4 billion years old.Finally in 1976, it was discovered that the earth is "really" 4.6 billion years old What happened?All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.
