Never been good at the math stuff so will leave that to others.
Just reading the questions makes my eyes cross!:S

Alana: Not quite...:-)

Whoops!

Anyone?
Take your time...have fun!

G'evening everyone:

Here's a question for all you out there to think about and formulate the answer:

Carbon-14 is a popular atom to look for when figuring out the age of old organic matter, for example, some bits of wood found in an old Egyptian tomb. Now, knowing that the half-life is only about 6,000 years, and the age of the Earth is about 4 billion (4*109) years, it doesn't take an Einstein to see that ALL of the carbon-14 should have converted to nitrogen long ago. Something must be PRODUCING the stuff even as we sit here staring at a computer monitor. Any ideas? 😀

Anyone? 😀

Cosmic rays.

Cosmic rays.

Bravo! Yes.

Producing C14:
Cosmic rays, which contain even higher levels of energy than ultraviolet light, cause some of the atoms in the upper atmosphere to fly apart into pieces. Neutrons that come from these fragmented molecules run into other molecules. When a neutron collides into a Nitrogen 14 atom, the Nitrogen 14 turns into Carbon 14 (A proton is also produced in the reaction as can be seen in the graphic to the left.). So in this reaction, a neutron is captured by the Nitrogen Atom and a proton is released. Thus in the Nitrogen Atom, a proton is effectively converted into a neutron, which allows a Carbon to be produced.

Two other reactions (Oxygen 17 reacting with neutrons, and He 4 reacting with Carbon 13) both produce Carbon 14, but with much smaller yields. It has been estimated that about 21 pounds of Carbon 14 is produced every year in the upper atmosphere.

So in addition to Carbon 12 and Carbon 13, which are both naturally occurring, Carbon 14 is also naturally occurring in our world. However, unlike both Carbon 12 and 13, Carbon 14 is unstable. The only reason why Carbon 14 continues to be found on Earth is because of its continued production in the upper atmosphere.
