DRIVING HAZARDS. The summit access road is approximately 10 miles long and has an altitude change of nearly 5,000 feet (1,510 m). There are many sections with a grade of 15 percent.
In simple terms, graphene, is a thin layer of pure carbon; it is a single, tightly packed layer of carbon atoms that are bonded together in a hexagonal honeycomb lattice. In more complex terms, it is an allotrope of carbon in the structure of a plane of sp2 bonded atoms with a molecule bond length of 0.142 nanometres.
In size the entire atom has been thought to be approximately four-billionths of an inch, meaning that approximately 250,000,000 atoms of this size must be put into line to span 1 inch. Atoms are not usually alone, but instead come in groups called molecules. Molecules A molecule is a single unit created by two or more atoms that are tightly bonded together. Diatomic molecules are molecules which are made of two atoms. Certain elements are diatomic elements because they do not naturally occur as single atoms, but as a pair of atoms. The diatomic molecules are (H 2) Hydrogen, (N 2) Nitrogen, (O 2) Oxygen, (F 2) Fluorine, (Cl 2) Chlorine, (I 2) Iodine and (Br 2) Bromine.
