Elements used in radioactive dating

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).The carbon-14 it contained at the time of death decays over a long period of time.By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.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.

Each chemical element, such as carbon and oxygen, consists of atoms unique to it.Geologists must first choose a suitable rock unit for dating.They must find rocks that contain these parent radioisotopes, even if they are only present in minute amounts.Unlike radiocarbon (Sm)—are not being formed today within the earth, as far as we know.Thus it appears that God probably created those elements when He made the original earth.
