Usually a solid conductor is a metal but there are exceptions.
For example graphite is nonmetallic but it conducts electricity.
Metals conduct electricity in the solid state due to the mobility of their free electrons. Nonmetals, on the other hand, do not conduct electricity in the solid state because they lack free electrons or have electrons that are tightly bound within their atomic structure.
In its solid state, potassium chloride consists of a regular lattice structure that does not have mobile ions necessary for conducting electricity. However, when potassium chloride is melted, the crystal structure breaks down, allowing the ions to move freely and conduct electricity.
Not in it's usual solid state. But sodium chloride will conduct electricity of molten or dissolved in water.
No, iodine is not a conductor in its molten state. Iodine is a non-metal and does not conduct electricity, whether in solid, liquid or gaseous state.
An ionic compound. Ionic compounds do not conduct electricity in their solid state because the ions are locked in place and cannot move to carry a charge. However, when melted, these ions are free to move and conduct electricity.
Ionic compounds conduct electricity only in the molten state because the ions are free to move and carry electric charge. In the solid state, the ions are held in fixed positions within the crystal lattice, preventing them from moving and conducting electricity.
Potassium is a very reactive metal, but being a metal, it conducts very well in the solid state. It does not have to be melted, but it will conduct in the molten state as well (but to a different extent).
In solid form, ionic compounds have their ions locked in a rigid lattice structure, making them unable to conduct electricity. When melted, the ions are free to move and conduct electricity because they are now mobile and can carry an electric charge.
solid nacl although contains ions and is an electrolyte does not conduct electricity because it does not have free valency electrons to move and thus the e- are bounded and this is the reason it does not conduct electricity
Iodine, either in its solid state or dissolved in alcohol, is not a conductor of electricity.
Uranium is a solid metal at room temperature.
Solid NaCl does not conduct electricity because its ions are locked in a fixed position and are not free to move. In order for a substance to conduct electricity, it needs to have free-moving charged particles (ions) that can carry an electric current. In the solid state, the ions in NaCl are held in a rigid crystalline structure, preventing them from moving and conducting electricity.
