Carbon nanotubes are actually just your everyday normal carbon atoms that are rolled in tubes. It's the atomic structure, not the chemical properties, that give it it's bulletproof strength.
Fluorine is an element. It occurs naturally.
Any man-made element was named after a today country.
This element is ununoctium (Uuo): atomic number 118.

Carbon nanotubes
Carbon nanotubes or graphene
Carbon in the form of diamond or nanotubes. Tin and Lead would be, but they are metals instead.
They're called "nanotubes".
Graphite is an allotrope of carbon.Nanonotubes can be made from many other materials.
the structure of nanotubes are carbon atoms joint together covalently to form a long tube.

Common macromolecules are hydro-carbon (hydrogen and carbon polymerized to macromolecules). For single element macro molecules, the example is carbon nanotubes.
Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.
According to Wikipedia: "The bulk modulus of superhard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal)." Note that diamonds are natural minerals; nanotubes are fabricated, making diamond the hardest known natural substance. You can read more about nanotubes, below.
Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.
