After another 5,730 years only half of those 50 (or 25 carbon-14 atoms would remain.) Think of the red ink molecules slowly disappearing at the same rate.

One day, about 5,000 years ago, most of the water suddenly drained from the pool.

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.

In this analogy, the red ink represents carbon-14 that forms in the upper atmosphere at the rate of 21 pounds per year and spreads throughout the biosphere.One of the nice things about this method is that we don't have to worry about carbon being lost from the sample.Because we are measuring the abundance of two isotopes of carbon, and because isotopes of the same element will be chemically identical, no ordinary process can preferentially remove C is going to be small enough to begin with, being only 0.0000000001% of atmospheric carbon, and then as the decay process progresses it's going to get smaller and smaller.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.
