Answer: 1) Graphite is soft and slippery because there are only weak intermolecular forces between its layers. Graphite is a good conductor of heat and electricity.
Which of the following is a good conductor of electric current Sulphur graphite silicon or diamond?
Graphite is a good conductor of electricity. Because here the electrons are loosely attacked the carbon atoms are held with very weak Van Der Waals forces of attraction. Hence, option (B) is correct. Silicon is a semiconductor and it will not conduct the electricity.
Which of the following is a good conductor of electric current?
So, all the elements gold, mercury and tungsten are a good conductor of electricity.
Which of the following is a good conductor of electricity graphite?
As a result, the correct answer is Option B i.e. graphite is a good conductor of electricity. Note: Graphite conducts electricity owing to the ‘spare’ electrons that have been delocalised in between the layers. Due to good conductivity, graphite is very useful as electrodes in case of electrolysis.
Is graphite a good 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.
Is Sulphur a good conductor of electricity?
Sulphur is a non-metal because it is consistent with three physical properties listed for non-metals. … It is a poor conductor of heat and electricity, because electrons are not free to move.
Which metal is the best conductor of electricity?
What Metal is the Best Conductor of Electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
- Copper. One of the most commonly used metals to conduct electricity is copper. …
Is fullerene a good conductor of electricity?
Fullerene is good cionductor of electricity but it is not as good as graphite. If we look at structure of Fullerene, there will be one free-moving electron moving about the structure. so it can conduct electricity but as compared to Graphite it can move easily.
Is Coke a conductor of electricity?
Coke. Coke is an amorphous form of carbon that burns without smoke. It is extremely pure with 98% carbon content. It is an amzing reducing agent and bad conductor of heat and electricity.
Is Silicon a conductor of electricity?
Silicon is a semiconductor, meaning that it does conduct electricity. Unlike a typical metal, however, silicon gets better at conducting electricity as the temperature increases (metals get worse at conductivity at higher temperatures).
Why NaCl is a bad conductor of electricity?
Solid [NaCl] is a bad conductor of electricity because the charged particles (ions) in solid [NaCl] are not capable of moving as they are bound by strong electrostatic forces. As a result, they can not conduct electricity. … As a result, they can not conduct electricity.
Is copper wire a good conductor of electricity?
The reason copper is used as electrical wiring is that it has one of the highest conductivity among metals. Hence copper is a good conductor of electricity so option (A) is correct.
