Radioactive dating is more accurate than relative dating because whichdatingsite com
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.
They have six protons in their nuclei and six electrons orbiting their nuclei, which gives carbon its chemical properties.
To achieve stability, these atoms must make adjustments, particularly in their nuclei.
In some cases, the isotopes eject particles, primarily neutrons and protons.
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.
Most people today think that geologists have proven the earth and its rocks to be billions of years old by their use of the radioactive dating methods. Given so much time, the ‘impossible’ becomes possible, the possible probable, and the probable virtually certain.
To understand how geologists “read” the age of a rock from these chemical analyses using the radioactive “clock,” let’s use the analogy of an hourglass “clock” (figure 2).
The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).
Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).
It is the number of neutrons in their nuclei that varies, but too many neutrons make the nuclei unstable, as in carbon-14.
Some isotopes of some elements are radioactive; that is, they are unstable because their nuclei are too large.
