Carbon is an element that is the found in abundance in the earth's crust.It is found in group 14 of the Periodic Table and has the atomic number 6.There are three allotropes of carbon, namely graphite, diamond and amorphous carbon.Carbon is a highly stable element that can combine with almost any other element to form a number of useful compounds. Arrange carbon atoms in one way, and they become soft, pliable graphite. — the atoms form diamond, one of the hardest materials in the world.Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber.Alchemists have often been dismissed as pseudoscientific charlatans but in many ways they paved the way for modern chemistry and medicine.
If facets are misaligned, the diamond may poorly reflect light.
Symmetry is graded from Ideal / Excellent, Very Good, Good, Fair, or Poor.
Symmetry grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry.
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.
