What makes a good conductor?
In a conductor, the outer electrons of the atom are loosely bound and can freely move through the material when an electric charge is applied. In general, the best electrical conductors are metals. Metals tend to have electrons in the outer layer of their atoms that are freely shared.
How do you know if an element is a good conductor?
The way to tell if any element is a conductor or insulator is to look at its position on the periodic table, namely the orbital electrons on the outer shells in reference to how readily they will pass or accept electrons loosely.

Who is the bad conductor of electricity?
Difference between Good Conductor and Bad Conductor of Electricity
Good Conductors | Bad Conductors |
---|---|
Example – Copper, Aluminium | Example – Rubber, Wood |
Can be used to make electric circuits. | Can not be used to make electric circuits. |
Is lemon juice a conductor?
Lemon juice contains citric acid. Because acids break up into charged anions and cations when dissolved in water, they conduct electricity because the charged particles are able to flow within the acid. -Therefore,it is good conductor.
Is salt water a conductor of electricity?
It sounds crazy, but it’s true! This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. These ions are what carry electricity through water with an electric current.
Is Earth a conductor?
Earth is a good conductor. The electrons are attracted to the sphere known as ground wire as it supplies a conducting path to the ground. The parts of the earth where there is no moisture acts as an insulator.
Is coconut oil a good conductor of electricity?
Coconut oil is a non polar liquid (when liquid) and does not have any free electrons which can move when you apply a potential (voltage) across it. The same chemical properties that make it so oil and water don’t mix makes it so oil cannot conduct electricity.
Can kerosene conduct electricity?
Answer. No, kerosene is not a good conductor of electricity. Explanation: Insulators are the substances which does not allow current or electricity to pass through it.
Is graphite a good conductor of electricity?
In a graphite molecule, one valence electron of each carbon atom remains free. Due to the free electrons in its framework, graphite can perform electricity. Therefore, graphite is said to be a good conductor of electricity.
Why graphite is soft and good conductor of electricity?
Graphite is soft lubricant and good conductor of electricity as it has pi bonds. The pi bonds of graphites are are one over another so it is soft lublicant and as it has pi bond so it can conduct electricity.
Why is graphite slippery?
Graphite has delocalised electrons, just like metals. The forces between the layers in graphite are weak. This means that the layers can slide over each other. This makes graphite slippery, so it is useful as a lubricant .
Why Graphite is a poor conductor of electricity?
Graphite is an allotrope of carbon. It has the properties of bot metals and non-metals. At higher temperature, graphite has an intermolecular structure with immobile ions. Thus, this makes graphite a poor conductor.
Is graphite a poor conductor?
In a graphite molecule, one valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Hence there won’t be flow of electrons That is the reason behind diamond are bad conductor electricity.
What makes graphite a good lubricant?
The carbon atoms are strongly bonded together in sheets. Because the bonds between the sheets are weak, graphite shows lower shearing strength under friction force. Thus it can be used as a solid lubricant and has become one of traditional and primary solid lubrication materials.
Are Diamonds conductors of electricity?
Diamonds do not conduct electricity. At these high concentrations, diamonds behave like a metal and become a good conductor of electricity. Boron doped diamonds (BDD) make excellent electrode materials with a larger electrochemical potential window in aqueous solutions than conventional electrode materials.
Why graphite is conductor but not diamond?
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. However, in diamond, all 4 outer electrons on each carbon atom are used in covalent bonding, so there are no delocalised electrons.
