Definition of radioactive dating in chemistry

Scientists have concluded that very little change has occurred in the ratio of Carbon-12 to Carbon-14 isotopes in the atmosphere meaning that the relationship between these two should be very similar to how they remain today.Without radiocarbon dating, “we would still be foundering in a sea of impressions sometime bred of inspired guesswork, but more often of imaginative speculation”.The carbon isotope is when absorbed by plants through photosynthesis and consumed by animals.Due to the way the sunlight reacts with the atmosphere, it is also taken in by respiration.However, carbon-14 dating offers something particularly valuable, called absolute dating, which is the age of the substance before the current time.This means that it may be used and compared to dates anywhere in the world.Uranium 238, a very unstable element, goes through 18 stages of decay before becoming a stable isotope of lead, lead 206.Some of the intermediate stages include the heavier elements thorium, radium, radon, and polonium.

Carbon- 14 is created when a neutron is excited by a cosmic ray, and then that neutron collides with a nitrogen atom.

This method of dating allows researchers to learn about past civilizations, changes in the earth, and in the climate.

Different civilizations and religions have different methods of dating.

In fact, it is considered the, “most important development in absolute dating in archaeology and remains the main tool for dating the past 50,000 years”.

With this tool, scientist hopes to unravel the mysteries of how man developed, when the first man lived, where he went, and create a type of timetable of human life.
