It is even used to make black ink for printers and painting.

Graphite is often used in making batteries, brakes, and lubricants.

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.

It is also used to make the writing (black) part of pencils.

Diamonds are used to make fine jewelry and are considered the most valuable of all the gemstones.

Radiocarbon dating uses isotopes of the element carbon. Cosmic rays – high-energy particles from beyond the solar system – bombard Earth’s upper atmosphere continually, in the process creating the unstable carbon-14. Because it’s unstable, carbon-14 will eventually decay back to carbon-12 isotopes.The unstable carbon-14 gradually decays to carbon-12 at a steady rate. Scientists measure the ratio of carbon isotopes to be able to estimate how far back in time a biological sample was active or alive.This plot shows the level of carbon-14 in the atmosphere as measured in New Zealand (red) and Austria (green), representing the Southern and Northern Hemispheres, respectively.is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly in each atom.It can be used on objects as old as about 62,000 years. Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.

If all samples in a batch are unsuitable for dating, we reserve the right to charge an inspection fee of NZD50 plus the MPI fee of NZD35.^ Measured by CRDS (precision 0.3 per mil).
