, some naturally occurring and some man-made: the air we breathe, the water we drink, the food we eat, the ground we walk upon, and the consumer products we purchase and use Radioactive Elements have large atomic numbers The more protons, the more unstable the atoms tend to be Atomic numbers above 83 are radioactive 10. Isotopes Isotopes of an element have the same number of protons, but different numbers of neutrons. Some isotopes are unstable, and radioactive This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate. The rate of decay (given the symbol λ) is the fraction of the 'parent' atoms that decay in unit time. For geological purposes, this is taken as one year Radioactive Decay: A stable nucleus of an element has the correct balance of protons and neutrons. Isotopes of an element which have too few or too many neutrons are usually unstable. Carbon-12 is stable but carbon-14 which has 2 extra neutrons is unstable. Nitrogen-14 is stable but its isotope, nitrogen-13 which has 1 neutron less is unstable

Radioactive decay is the process in which a radioactive atom spontaneously gives off radiation in the form of energy or particles to reach a more stable state. It is important to distinguish between radioactive material and the radiation it gives off.. Types of Radiation: There are four types of radiation given off by radioactive atoms So, you can use the radioactive elements to measure the age of rocks and minerals. Below is a list of some common elements. Their useful range is from about 1/10 their half-life (the time it takes for half of the radioactive element/isotope-- the parent, to convert into a non-radioactive element/isotope-- the daughter) to 10 times their half-life Radioactive decay is a random process at the level of single atoms, in that, according to quantum theory, it is impossible to predict when a particular atom will decay. In other words, a nucleus of a radionuclide has no memory. There are three basic modes of radioactive decay: Alpha decay. Beta decay. Gamma decay
