The rate of decay is considered constant and measurable, and is expressed by the term “half life.”Half life can be understood, for our purpose, by thinking of a block of ice. The time it takes to melt until it weighs only 5 pounds (half the original weight) is called its “half life.” For this example, let’s say the ice takes five hours to melt from 10 pounds down to 5 pounds. This is not exactly the way C-14 acts, but it serves our purpose.Unlike ice melting, the half life of carbon and other unstable elements is constant.
This is one of the difficulties for those relying on carbon dating.It would take 30,000 to 50,000 years to go from zero C-14 until equilibrium is reached.Since scientists accept the concept of evolution, they conclude that the atmosphere is millions of years old.It would take an additional 5,730 years for the 50 pounds to decay to only 25 pounds, and so on, halving the amount of C-14 every 5,730 years.When C-14 is formed, it begins to break down into nitrogen as it loses an electron from the nucleus.A basic quality of C-12, the most prevalent form of carbon, is stability—it doesn’t change.
C-14, however, is unstable and begins changing immediately after it is formed.
Since C-14 equilibrium would certainly have been reached in the first 50,000 years, it is millions of years ago.
When carbon-14 dating was first utilized, it was based on the idea that the amount of C-14 was, in fact, stable and unchanging and, therefore, the ratio between C-12 and C-14 was thought to be constant. It was discovered that C-14 equilibrium had not yet been reached.
Some of the neutrons react with the nitrogen-14 near them and form carbon-14 and an extra (free) proton.
Remember, once C-14 is produced, it immediately begins to decay, so C-14 is decaying at the same time it is being made.
The ratio of C-12 to C-14 is approximately 1 billion to one in today’s atmosphere.
