Graphene is a crystalline allotrope of carbon with 2-dimensional properties. Its carbon atoms are densely packed in a regular atomic-scale chicken wire (hexagonal) pattern. Each atom has four bonds, one σ bond with each of its three neighbors and one π-bond that is oriented out of plane.

Carbon is a soft, dull gray or black non-metal that you can scratch with a fingernail. Th density of carbon as graphite is 2.267 g/mL, which means it will sink in water. Chemical Properties: Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide).

Matter is anything that takes of space and has matter Physical properties of matter are: mass, physical state (solid, liquid, and gas), solubility (mixtures and solution), density (sinking and floating), magnetism, insulation/conduction, and measurement. Some physical properties are observed and some are measured.

The physical and chemical properties of carbon depend on the crystalline structure of the element. Its density fluctuates from 2.25 g/cm³ (1.30 ounces/in³) for graphite and 3.51 g/cm³ (2.03 ounces/in³) for diamond. The melting point of graphite is 3500ºC (6332ºF) and the extrapolated boiling point is 4830ºC (8726ºF).
