One allotrope of this element found at the Tunguska impact site has a hexagonal lattice structure and is called Lonsdaleite.
One allotrope of this element found at the Tunguska impact site has a hexagonal lattice structure and is called Lonsdaleite. This element is produced in stars via the triple-alpha process, and another of its allotropes with an amorphous arrangement is a useful solid lubricant. (*) Fullerenes such as buckyballs are composed only of this element. Its isotope with mass number 14 is commonly used in radiometric dating. Name this element which composes diamond and graphite, has atomic number six, and chemical symbol C.
