Carbon-14 is also passed onto the animals that eat those plants.After death the amount of carbon-14 in the organic specimen decreases very regularly as the molecules decay.

Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies.

There are three main types of radiation or radioactive decay depending on the isotope.

When isotopes are unstable they emit energy in the form of radiation.

Stable and Unstable Isotopes Elements can be made up of different isotopes. Different Types of Radioactivity How is it measured?

Isotopes are atoms with the same number of protons and electrons, but a different number of neutrons. These are the elements that we see around us and find in nature. Radioactivity is measured using a unit called the "curie". The curie measures how many atoms spontaneously decay each second.

Diamonds are also used for their hardness in cutting tools and precision instruments. People have known about carbon as a substance since ancient times.

French scientist Antoine Lavoisier determined that diamond was made of carbon in 1772. Carbon gets its name from the Latin word "carbo" meaning charcoal or coal.

Carbon is the fourth most abundant element in the universe by mass and the second most abundant element in the human body.

Carbon is constantly cycled through the Earth's oceans, plant life, animal life, and atmosphere. Characteristics and Properties Carbon is found on Earth in the form of three different allotropes including amorphous, graphite, and diamond.

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.

Isotopes There are two stable naturally occurring isotopes of carbon, carbon-12 and carbon-13.
