In 1772 he pooled resources with other chemists to buy a diamond, which they placed in a closed glass jar.They focused the sun’s rays on the diamond with a remarkable giant magnifying glass and saw the diamond burn and disappear.At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga.Et harum quidem rerum facilis est et expedita distinctio.The fraction of the radiation transmitted through the dead skin layer is estimated to be 0.11.Small amounts of carbon-14 are not easily detected by typical Geiger–Müller (G-M) detectors; it is estimated that G-M detectors will not normally detect contamination of less than about 100,000 disintegrations per minute (0.05 µCi). The decay of radioactive isotopes at known rates can be used to measure the age of something (like a rock) in absolute time (number of years).

This can be done with a degree of ease for the first 20 elements following several simple steps.In 1779, Swedish scientist Carl Scheele showed that graphite burned to form carbon dioxide and so must be another form of carbon.In 1796, English chemist Smithson Tennant established that diamond was pure carbon and not a compound of carbon; it burned to form only carbon dioxide.Under very hot temperatures — greater than 100,000,000 Kelvin (179,999,540.6 F) — the helium nuclei begin to fuse, first as pairs into unstable 4-proton beryllium nuclei, and eventually, as enough beryllium nuclei blink into existence, into a beryllium plus a helium.The end result: Atoms with six protons and six neutrons — carbon.

Arrange carbon atoms in one way, and they become soft, pliable graphite. — the atoms form diamond, one of the hardest materials in the world.
