What do you get when you subtract one proton from nitrogen? But not any old carbon – you get a radioactive form called carbon-14 (the number ’14’ is the number of protons and neutrons the isotope has).During photosynthesis plants turn carbon dioxide into sugar.There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.Radiocarbon dating may only be used on organic materials.Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon 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.It can be used on objects as old as about 62,000 years.

Some of these particles collide with atmospheric nitrogen and knock off one of its protons.This is a concern because as the global CO2 levels increase, so does the acidity of rain, the ocean, and freshwater.
