Atoms of the same element with differing atomic weights are called isotopes.Radioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter).The next 40 years was a period of expanding research on the nature and behavior of atoms, leading to the development of nuclear fission and fusion as energy sources.A byproduct of this atomic research has been the development and continuing refinement of the various methods and techniques used to measure the age of Earth materials. 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.Other factors and basic assumptions must also be considered.Of course, Kelvin formed his estimates of the age of the Sun without the knowledge of fusion as the true energy source of the Sun.We will deal with carbon dating first and then with the other dating methods.Carbon has unique properties that are essential for life on Earth.
It can be determined by looking at the position of rock layers.
(Hint: The Law of Superposition might help you.) According to the Law of Superposition newer rock layers form on top of already existing layers.
