One example is diamond. It has a high melting point due to its strong covalent bonds, does not conduct electricity as it lacks free electrons or ions, and is insoluble in water due to its nonpolar nature and strong bond structure.
Ionic compounds will have a high melting point and conduct electricity when melted or dissolved in water due to their ability to form charged ions that can carry electric current.
The ability to conduct electricity in the solid state is not a common property of ionic compounds, as they typically only conduct electricity when molten or in solution.
Graphite is an example of a substance that has a high melting and boiling point and can conduct electricity. It has a layered structure that allows for the easy movement of electrons, which is why it can conduct electricity despite being a non-metal.
Sodium chloride fits this description. It has a melting point of 1074 K and conducts electricity when dissolved in water as it dissociates into sodium and chloride ions, but does not conduct electricity in the solid state because the ions are not free to move.
have lower melting and boiling points, exist as discrete molecules, and do not conduct electricity in the solid state.
One example of a substance fitting this description is diamond. Diamond is a natural crystalline solid that does not dissolve in water, does not conduct electricity, and has a melting point of around 3550°C.

They do not conduct electricity 2.They are not malleable 3.They have low melting and boiling point.4.They are bad conductors of heat.
Yes, lead does conduct electricity when melted. In its molten state, lead becomes a good conductor of electricity due to the free movement of its electrons. This property is why lead is often used in various electrical applications, such as soldering.
B. has a low melting point is NOT a characteristic of an ionic compound. Ionic compounds typically have high melting points due to the strong electrostatic forces between the ions in the crystal lattice.
Pure aluminium oxide is mixed with cryolite in electrolysis of aluminium because cryolite lowers the melting point of the mixture, making the process more energy-efficient. This allows the aluminium oxide to dissolve in the molten cryolite and conduct electricity more easily, leading to the extraction of aluminium metal from the ore.
