Mercury is a poor conductor of heat, but a fair conductor of electricity. Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. As a result, mercury forms weak bonds and is a liquid at room temperature.
Does mercury conduct electricity in solid state?
Mercury is a heavy, silvery-white liquid metal. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. … Solid mercury is malleable and ductile and can be cut with a knife.
What is the best conductor of electricity in the solid state?
Best to Worst – Which Metal is the Best Conductor of Electricity
Why is mercury not a good conductor of electricity?
Heat energy is conducted by transferring energy of atoms vibrating at high level. … Since high density of mercury, there is no enough room for vibrating mercury atoms. So it can’t be heated easily. So it’s a poor conductor of electricity.
Can conduct electricity in the solid state?
Covalent compounds (solid, liquid, solution) do not conduct electricity. Metal elements and carbon (graphite) are conductors of electricity but non-metal elements are insulators of electricity. … Ionic compounds do not conduct electricity in solid state as the ions are not free to move.
Does mercury have conductivity?
Mercury is the only metal which is liquid at room temperature. Two others melt close to room temperature (cesium at 28.5°C and gallium at 29.8°C). Because of its unreactivity, fluidity, high density, and high electrical conductivity, it finds many uses in scientific apparatus.
Does mercury conduct electricity through electrons?
Yes Mercury conducts electricity because it’s a metal because of its free electrons. Mercury is in liquid form.
Which among iron and mercury is a better conductor?
Among iron and mercury which is a better conductor of electricity and why? Answer: … Iron is a better conductor of electricity than mercury because the resistivity of mercury is more than the resistivity of iron.
What 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. …
What types of solids conduct electricity?
Solid metals conduct electricity and heat, while ionic solids do not.
Why is mercury a good conductor?
We know that mercury has a large value of the coefficient of thermal expansion. Hence, even the smallest change in temperature is evident in the shape of the mercury container. … All these factors make mercury a good conductor of heat and this is why it has a large application spectrum especially in measuring devices.
Is mercury an insulator or conductor?
Mercury is a conductor as it can conduct heat well.
Where is mercury used as a conductor?
Why is mercury used in thermometers despite being the poorest conductor of heat? Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion.
Which of the following Cannot conduct electricity in solid state?
Iron conducts electricity in solid state but iron (III) chloride is an ionic compound and these compounds do not conduct electricity in solid state.
What conducts electricity in the liquid state but not in the solid state?
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
Which of the following solids Cannot conduct electricity?
iodine is a non- polar molecular solid iodine moleculas are held together by london force or dispersion force , this is soft and non – conductor fo electricity . Water is a hydrogen bonded molecular solid in which H and O are held together by to non – ionic nature , they are not electrical conductor.
