Process o radioactive dating
Archaeologists, geologists, physicists can choose between array of radioisotopes Let us quote the words of one scientist: “We must appreciate the immense favour Nature has done us in providing a table of elements bursting with radioactive clocks capable of functioning over a wide range of timescales.
These timescales are associated with elements of vastly differing physical and chemical properties, deeply embedded in many processes going from the inert to the living, from the scale of the mineral to that of our planet.” Radiocarbon corrections for accurate dating The changes that have occurred in the Earth’s magnetic field should be taken into account for Carbon 14.
Each atom is understood to be made up of three basic parts.
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.

Numbers do not necessarily match those in definitions.The moment the coral dies, however, the decay of radioactive elements begins to produce thorium 230 inside the coral.The amount of thorium 230 found in the dead coral allows to measure how long it have been dead. For decades, the biologists have boldly proclaimed that, whereas we cannot observe today one type of creature evolving into a totally different type of creature, “Time is the hero of the plot. No one even bothers to ask what assumptions drive the conclusions.
