Diamond and silica can not conduct electricity, because there are no free electrons. Graphite can conduct electricity, because there are free electrons between the layers of graphite. Solubility… Covalent network compounds are not soluble in water, as the
Graphite forms three covalent bonds so each carbon atom has a free (delocalised) electrons between the layers which can carry charge so it can conduct electricity Diamonds form four covalent so there are no delocalised electrons therefore electricity cannot be conducted
Graphite and silicon carbide are types of covalent crystals whose crystal lattice is held in place by strong covalent bonds. Answer and Explanation:
11. Diamond, graphite, silicon dioxide. 12. Graphite can conduct electricity because of the delocalised (free) electrons in its structure. These arise because each carbon atom is only bonded to 3 other carbon atoms. This leaves 1 electron to become
The 4th electron becomes delocalised and these electrons produce weak van der Waals forces between the layers. In Diamondeach carbon atom is strongly (covalently) bonded to 4 others. Carbon atoms cannot slide. Graphite can conduct electricity but diamond cannot.
Only in graphite is electrical conductivity observed but as expected it is very low. Both silicon and germanium exist in distorted diamond-like lattices, with germanium’s structure more distorted than silicon’s. The larger the atom, the greater the deviation of its
In a way, graphite is a bit similar to copper. They are both soft and malleable, and can conduct electricity. Like copper, graphite is also used in polishes and paints. Graphite can withstand the heat generated by electricity running through its atoms.
Graphite has properties which are ideal for making the contacts in an electric motor. Explain, in terms of structure and bonding, why graphite has these properties
1/4/2020· Graphite is a good conductor of electricity because its electrons are delocalized or free to move around. Graphite is structured into planes with tightly bound atoms. There is a great deal of distance between planes, and they are bonded weakly together, allowing the electrons to move around.
With graphite and metal, electrical conduction is made possible by electrons which have been delocalized, which means they’re not firmly bound to any specific atom. Since these electrons are not bound, they’re free to roam, which is how the electrical current gets carried through most materials.
Graphite on the other hand, although also only made up of carbon atoms, is the only non-metal that can conduct electricity. This is because only 3 of the available valence electrons form covalent bonds leaving 1 spare electron, which then becomes delocalised.

30/4/2021· Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct …
30/4/2021· Yes, Silicon conducts electricity as it is a semiconductor. The conductivity of Silicon gets better with increasing the temperature of it. This is because of the unique property of semiconductors whereas, in the case of metals, the conductance of electricity decreases with an increase in temperature. Silicon is used in many electronics appliances
Graphite consists of several 2−D layers of covalently bonded atoms stacked together. Their configuration in this substance allows electrons to flow freely and thus conduct electricity, which is the flow of electrons from one place to another. Hence, graphite is a good conductor of electricity.
Graphite conduct electricity well in a direction parallel to the planes of hexagons, but not a tall well in a direction perpendicular to the planes Reason In graphite s p 2 hybridisation and due to presence of free electron they are good conductor of electricity in a layer but not so good in between two layers.
Graphite is an electrical conductor, hence useful in such appliions as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

In diamond the carbon atoms are bonded to four other atoms. Whereas, in graphite each carbon atom is only bonded to three other atoms. Therefore, there are delocalised (free) electrons in graphite, which can move and carry a charge so graphite conducts electricty. Answered by Sophie S. • Chemistry tutor.
Graphite is a good conductor of electricity due to its free delocalized electron which is free to move throughout the sheets. Graphite is insoluble in organic solvents and water, this is because the attraction between solvent molecules and carbon atoms is not strong enough to overcome the covalent bonds between the carbon atoms in the graphite.

4/8/2015· Graphite conducts electricity because it possesses delocalized electrons in its structure. The honeyco layout of the stacked carbon atoms of graphite leaves a single electron unbound in each hexagon. Each of these electrons is free to move within the

Very high melting points – this is because a lot of strong covalent bonds must be broken. Graphite, for example, has a melting point of more than 3,600°C. Variable electrical conductivity – diamond does not conduct electricity, whereas graphite contains free electrons so it does conduct electricity.
