Carbon dating validity

Carbon-dating Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.

These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.

Ninety-nine percent of these also contain six neutrons.

The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.

We will deal with carbon dating first and then with the other dating methods.

Carbon has unique properties that are essential for life on Earth.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.

A favorite tactic of Young-Earthers involves citing studies which show trace amounts of Indeed, this results from a unique decay mode known as "cluster decay" where a given isotope emits a particle heavier than an alpha particle (radium-226 is an example.) This fact is extremely inconvenient to them, and creationist literature, accordingly, usually does not mention it.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

But I realized the other day that even as an adult with a fair amount of scientific knowledge, I could not articulate exactly how or why carbon dating works.

So I did a bit of research to fill in the gaps in my understanding, and not surprisingly I found the details to be quite interesting.
