Is carbon 14 an absolute dating technique?
Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms. Radiocarbon dating is essentially a method designed to measure residual radioactivity.
Who discovered Carbonday?
Willard Libby Radiocarbon dating/Inventors Professor Willard Libby, a chemist at the University of Chicago, first proposed the idea of radiocarbon dating in 1946. Three years later, Libby proved his hypothesis correct when he accurately dated a series of objects with already-known ages.

What are the properties of carbon 14?
carbon-14, the longest-lived radioactive isotope of carbon, whose decay allows the accurate dating of archaeological artifacts. The carbon-14 nucleus has six protons and eight neutrons, for an atomic mass of 14.
How do we know the suns age?
4.603 billion years Sun/Age
The three relatively well-known allotropes of carbon are amorphous carbon, graphite, and diamond.
Where is carbon 12 found?
Carbon-12 (12C) is the more abundant of the two stable isotopes of carbon (carbon-13 being the other), amounting to 98.93% of the element carbon; its abundance is due to the triple-alpha process by which it is created in stars.
