At STP, both diamond and graphite are solids composed of carbon atoms. These solids have(1) the same crystal structure and same properties
(2) the same crystal structure and different properties
(3) different crystal structure and same properties
(4) different crystal structure and different properties
The answer is (4). The crystal structure of diamond is a strong network of atoms. And structure of graphite is organized in layers. Due to the different crystal structure, they have the different properties.
