John is assisting a geologist who has traveled across the world and collected a few samples. He asks John to classify the samples that can be dated using carbon-14 and uranium-235 (or U-235). All organic materials contain carbon and are dated using C-14; inorganic materials are dated using any radioactive element, such as uranium, rubidium, potassium, and thorium, except carbon. Now, help John group the samples.

The soon-to-be mummy was placed in natron (naturally occurring salt) and left to dry for 40 days.

After the flesh was dehydrated, the body was wrapped in layers upon layers of linen, between which priests placed amulets to aid the newly deceased in the afterlife.

How is carbon-14 used for dating?

The basis of radiocarbon dating is simple: all living things absorb carbon from the atmosphere and food sources around them, including a certain amount of natural, radioactive carbon-14.

When the plant or animal dies, they stop absorbing, but the radioactive carbon that they've accumulated continues to decay.

What is the principle of carbon dating?

Radiocarbon dating works by comparing the three different isotopes of carbon.

Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.

This means that although they are very similar chemically, they have different masses.
