Which substance is a good conductor of electricity in both solid and liquid states?

Which substance is a good conductor of electricity when solid and liquid?

Ionic solids are usually quite soluble in water, and the water solutions of ionic solids are good conductors of electricity because of the freedom of the ions to migrate through the solution.

Which substance will conduct electricity in both solid and liquid phase?

5) Which substance will conduct electricity in both the solid phase and the liquid phase? 7) Which of the following solid substances contains positive ions immersed in a sea of mobile electrons?

Substance A Substance B
Solubility in Water nearly insoluble soluble
Hardness soft, waxy crystals hard crystals

Which substance conducts electricity in both solid and molten state?

Sodium’s sea of delocalized electrons among the unipositive ions present in the structure is what gives it its conductivity. These delocalized electrons are present in both a solid and molten state, therefore sodium can conduct electricity in both states.

What type of substance is a good conductor of electricity in all phases?

Answers. All the metals conduct electricity well. You should explain this conductivity in terms of the ‘free’ electrons within a metallic structure.

Does an alloy conducts electricity both when solid and molten?

Metals conduct electricity both when solid and when molten. This is because the delocalised electrons are mobile. Covalently bonded substances with a simple molecular structure do not conduct electricity. This is because they have neither ions nor electrons that are mobile.

What are 2 substances that conduct electricity?

The most effective electrical conductors are:

  • Silver.
  • Gold.
  • Copper.
  • Aluminum.
  • Mercury.
  • Steel.
  • Iron.
  • Seawater.

Which substance can conduct electricity in the liquid phase but not in the solid phase?

Which type of substance can conduct electricity in the liquid phase but NOT in the solid phase? An ionic compound.

Which types of substances can conduct electricity as solids?

There are two types of substances that are good conductors or electricity. Metals conduct in the solid phase because they contain electrons that are mobile, or free to move around. When a copper wire is used in an electrical circuit it has electrons moving through it whenever the switch is closed.

What type of substance is a good conductor?

Most familiar conductors are metallic. Copper is the most common material used for electrical wiring . Silver is the best conductor, but it is expensive. Because gold does not corrode, it is used for high-quality surface-to-surface contacts.

Why is sodium a good conductor of electricity?

Solid sodium is good conductors of electricity as in sodium there is no band gap between the valence band and conduction band as they overlap with each other. The electrons are continuously available in the closed orbital which can conduct electricity. … Therefore, the ionic crystal of sodium chloride is an Insulator.

Which of the following substances have good electrical conductivity in the molten and in the aqueous form?

Electrolytes are compounds that can conduct electricity in molten or aqueous solution. Examples of electrolytes are acids, alkalis and salts dissolved in water or molten salts. All these are ionic substances.

Is Aluminium good conductor of electricity?

Aluminum. Aluminum is yet another metal known for its high conductivity of electricity. Though by volume its conductivity is only 60% of copper, by weight, one pound of aluminum has the electrical current-carrying capacity of two pounds of copper. … Aluminum is often used in satellite dishes.
