Isotopic dating is based on

isotopic dating is based on-78

This process of changing one element (designated as the parent isotope) into another element (referred to as the daughter isotope) is called radioactive decay.

Most people would assume that the “clock” started half an hour earlier.These variations are called isotopes of that element.While the number of neutrons varies, every atom of any element always has the same number of protons and electrons.After all, textbooks, media, and museums glibly present ages of millions of years as fact.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions.Note that the carbon-14 (or radiocarbon) method is not used to date rocks because most rocks do not contain carbon. They must find rocks that have the isotopes listed above, even if these isotopes are present only in minute amounts.

Most often, this is a rock body, or unit, that has formed from the cooling of molten rock material (called magma).

Orbiting around the nucleus are electrons (tiny particles each with a single negative electric charge).

The atoms of each element may vary slightly in the numbers of neutrons within their nuclei.

Actually, it isn’t really a decay process in the normal sense of the word, like the decay of fruit.

The daughter atoms are not lesser in quality than the parent atoms from which they were produced.

Both are complete atoms in every sense of the word.
