Which of the following statements is true about the structure of graphite?
It is made up of hexagonal rings of carbon atoms.
It is made up of sheets of carbon atoms arranged in a three-dimensional structure.
It is made up of sheets of carbon atoms arranged in a two-dimensional structure.
It is made up of randomly arranged carbon atoms.
Graphite has a layered structure, where each layer is made up of carbon atoms arranged in a hexagonal lattice. These layers are only weakly bonded to each other, which allows them to slide past each other easily, making graphite soft and slippery.
