Whereas, in graphite the carbon atoms only form 3 covalent bonds, creating hexagonally packed sheets of carbon. Specifically, it is made of sp 2 bonded carbon atoms that have a molecule bond length of 0.142 nm between atoms. 4. Perhaps, because it is a layered structure, graphite is soft.
The sheets of carbon become bonded by weaker intermolecular forces. Graphite is soft and slippery because its carbon atoms are bound together by weak bonds known as Van der Waal forces.
Now, the part that makes the graphite softer than diamond is that the flat 'sheets' of carbon are bonded together by a much weaker bond than covalent bonds , called Van Der Waals forces. Graphite is soft and good conductor because of the electron delocalisation of carbon layers. Just like diamond or graphite, graphene is an allotrope of carbon. It is soft because there is no bonding between the flat, parallel plates.
Graphite is layers and layers of graphene piled up on top of each other with weak molecular bonds between the layers - therefore the layers shift and slide over each other, and the overall material appears soft at human scale. Graphite is a good conductor of heat and electricity. And it is hard to even talk about bulk graphene because by definition it is a single layer or a very thin bundle of layers. The bonds that connect the carbon atoms in graphite are very weak, so they are easily broken, which makes graphite seem soft and slippery. However the electricity is primarily conducted within the planes. It has a metallic luster and is opaque to light. 3. Graphite is a soft, slippery, grayish-black substance. Anyway, please refine your question. So bulk graphite isn't just brittle but also soft as some orientations will slide easily around. 2. 0 0 0 It's melting point is high because each plate is a network solid with lots of bonding between carbon atoms. Specific gravity of graphite is 2.3. It is because of these weak intermolecular forces that the layersof graphite can slide over eachother, making the overall substance a lot weaker than diamond. Graphite is a non-molecular species, and consists of an infinite array of carbon atoms, covalently bonded in 2 dimensions. It was originally thought to be a form of lead. As a non-molecular species its melting point is impossibly high. Since it has weak intermolecular forces, graphite would be slippery and soft enough to act as a lubricant. Get an answer to your question "Why graphite is soft and good conductor of electricity ..." in Chemistry if there is no answer or all answers are wrong, use a search bar and try … These valence electrons are free to move so it able to conduct very well. Graphite (/ ˈ ɡ r æ f aɪ t /), archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.It occurs naturally in this form and is the most stable form of carbon under standard conditions.Under high pressures and temperatures it converts to diamond.Graphite is used in pencils and lubricants.
