A substance that conducts electricity is a conductor. There is no special name for one that is solid; if you need to specify that it is solid, just call it a "solid conductor".

no
No, covalent compounds do not conduct electricity as solids because the electrons are held tightly in the atoms and are not free to move and carry an electric charge. This is in contrast to ionic compounds, where the ions are free to move and conduct electricity when dissolved in water or when molten.
Solids can definitely conduct electricity -- like copper wires. It is a general property of metals.
Electrolytes
Ionic solids do not conduct electricity in their solid state because their ions are not free to move and carry electric charge. However, when they are melted or dissolved in water, the ions become free to move and conduct electricity.
Ionic solids are poor conductors of electricity because the ions in the solid are not free to move and carry an electric charge. In ionic solids, the positive and negative ions are locked into a rigid crystalline lattice and cannot move freely to conduct electricity. Only when the ionic solid is melted or dissolved in water do the ions become mobile and able to conduct electricity.
Ionic compounds conduct electricity when they are dissolved in water or melted, allowing the ions to move and carry electric charge. Solid ionic compounds do not conduct electricity because the ions are fixed in place and unable to move to carry charge.
Yes, electricity can travel through solids and liquids as they contain charged particles that can conduct electricity. However, gases are poor conductors of electricity as they have fewer free-moving charged particles than solids and liquids.
Insulator
Ionic solids are generally bad conductors of electricity in their solid state because their ions are held in a fixed position by strong electrostatic forces. However, when ionic solids are melted or dissolved in water, they can conduct electricity due to the mobility of their ions.
