GIANT COVALENT STRUCTURES - chemguide
3/10/2018· conducts electricity. The delocalised electrons are free to move throughout the sheets. If a piece of graphite is connected into a circuit, electrons can fall off one end of the sheet and be replaced with new ones at the other end.
Does Water Conduct Electricity? Is It a Conductor Or an …
In fact, this is the primary reason why water + electricity is such bad news, as it can cause electric shocks to those who come in contact with the dangerous pair. However, if you really think about it and dig into the depths of chemistry on this question, you’d see that pure water is actually not a good conductor of electricity.
AQA GCSE (9-1) Chemistry for Coined Science: Trilogy …
This is similar to the way that delocalised electrons move in metals. This is why both graphite and metals can conduct electricity. Diamond has no delocalised electrons so cannot conduct
why graphite ( carbon ) rods are used as electrodes in …
15/9/2011· Carbon - the most important reason is that graphite conducts electricity! As for LiCl, it will conduct as it cools down to the freezing (melting) point. If it conducts after that, it is because lithium metal is now short-circuiting the electrodes.

Unit 2 notes -2022 English
3) Graphite is a good conductor of electricity. Explain the reason. 4) Graphite conducts electricity only along the layers, but not in right angles to the layers. Explain 5) Graphite is used as a lubricant in some machineries. Explain the reason. 6) Graphite is used
Structure of Diamond and Graphite, Properties - Basic …
1/11/2017· Graphite conducts electricity due to the electron delocalization of its pi electrons where as diamond as an electrical insulator due to its localized valence electrons; however, diamond is
3.3.3: Graphite - Chemistry LibreTexts
To explain the fact that graphite conducts electricity, we use an idea from molecular orbital (MO) theory, namely that bonding and antibonding MOs are formed from the adjacent p orbitals that extend over the sheet surface.
Why graphite conduct electricity when it is a covalent …
First, graphite is not a compound, it is an allotrope of elemental carbon. The conductivity of graphite is due to a property call resonance. In a covalent doublt bond there are two types
Why do metals conduct heat and electricity so well?
Why metals conduct heat and electricity, what metals conduct the best Silver has a larger atomic radius (160 pm) than gold (135 pm), despite the fact that gold has more electrons that silver! For a reason for this see the comment below.

Examples of Electrical, Thermal Conductors & Insulators
29/1/2019· However, there are exceptions, so don''t assume just because a sample conducts (insulates) one form of energy that it behaves the same for other forms! Metals typically conduct both heat and electricity. Carbon conducts electricity as graphite, but insulates as
Graphite is a non - metal. But still it conducts ele …
Graphite is a non metal but still can conduct electricity because of the delocalised (free) electrons in its structure. This is because each carbon atom in graphite is bonded to only three other carbon atoms and its fourth valence electron is free.
