Nitrogen fossils dating - dating for ivy leaguers

The carbon-14 atoms combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.

While an organism is alive this exchange of Carbon continues, and the percentage of Carbon-14 in its body is the same as the percentage of Carbon-14 in the atmosphere.

Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

This is used to date the remains of things that were once living.

All living things absorb Carbon from the atmosphere into their bodies, and excrete Carbon back into the environment.

Once the rock cools and solidifies, Argon that is formed by radioactive decay is trapped inside.

As no Argon was present in the rock when it first solidified, all Argon in the rock is due to the radioactive decay of Potassium.

When these energetic neutrons collide with a nitrogen-14 (seven protons, seven neutrons) atom it turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).

Since Nitrogen gas makes up about 78 percent of the Earth's air, by volume, a considerable amount of Carbon-14 is produced.

Radioactive decay allows geologists and physicists to measure the age of ancient fossils, rocks and even the Earth.

This process is called radiometric or radioactive dating.

By measuring the amounts of Potassium and Argon present we can date volcanic rocks that are millions of years old.
