They are bonded by nonpolar covalent bonds. Each of the atoms is sp2 hybridized. It is sometimes depicted as having alternating single and double bonds, but this is not quite accurate. The bonds are subject to what is called resonance so that the bonds are neither single nor double but sort of in between.

Why is diamond so much harder then graphite?
Diamond is so much harder than graphite because the carbon atoms in diamond are bonded to other carbon atoms tetrahedrally. In graphite, the carbon atoms are only bonded to three other carbon atoms and form sheets. There is one valence electron that wanders the surface which makes graphite a conductor.
How are the carbon atoms arranged in graphite?
The atoms are bonded together in a rigid network which makes diamond very hard. Each carbon atom forms 4 covalent bonds
Lead of a pencil made up of what?
Generally it's made of graphite. Graphite is a substance made of carbon. The carbon atoms are bonded together in a particular way that allows "sheets" of graphite to break off easily. When you write something, some of these sheets break off and end up on your paper.
What is special about carbon atoms that they can make so many kinds of molecules?
Carbon atoms can be bonded together.
How many bonds hold the carbon atoms together in graphite?
three

Why do diamond and graphite have different physical properties even though they are both entirely composed of carbon?
Since the chemical properties remain same,The physical structural form of carbons varies in both diamond and graphite.Here diamond is called as the strongest substance ever known.graphite is a good conductor on electricity as it gives out one free electron for generating electricity.

How many carbon atoms are sometime bonded together to form a ''carbon''?
skeleton
How can diamond and graphite be made out of same substance and be so different?
They are so different because of the way the carbon atoms bond to each other. Graphite has layers of very strong bonds, but the layers are very weakly bonded to each other. Diamonds are so strong because all of its carbon atoms are uniformly bonded to one another.
Is charcoal an ionic compound?
Nope! charcoal is not a pure substance and a major constituent is graphite which is a form of elemental carbon ( an allotrope of carbon). the chmisl bonding in graphite is covalent as the atoms bonded together have the same electronegativity.
Is Graphite an Ionic Compound?
No, it is a pure form of the element carbon composed of sheets of covalently bonded atoms.
Number of adjacent carbon atom in graphite?
In a graphite structure, three adjacent carbon atoms are bonded to every carbon atom.
What is lead in pencil?
Graphite is present in pencil leads. it is composed of carbon atoms covalently bonded with each other, and 1 free valence electron in each atom (which explains why graphite/pencil-lead conducts electricity)
