Elements used in radioactive dating

So, for example, every carbon atom contains six protons and six electrons, but the number of neutrons in each nucleus can be six, seven, or even eight.Therefore, carbon has three isotopes, which are specified as carbon-12, carbon-13 and carbon-14 (figure 1). Comparison of stable and unstable atoms of the element carbon.For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.This process of changing the isotope of one element (designated as the parent) into the isotope of another element (referred to as the daughter) is called radioactive decay.Thus, the parent isotopes that decay are called radioisotopes.In some cases, the isotopes eject particles, primarily neutrons and protons.

It is the number of neutrons in their nuclei that varies, but too many neutrons make the nuclei unstable, as in carbon-14.So let’s take a closer look at these methods and see how reliable they really are.Each chemical element, such as carbon and oxygen, consists of atoms unique to it.Each atom is understood to be made up of three basic parts.The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).
