Answer:
Metallic element are conductors, because it shows north and south pole. Nonmetallic elements are generally non-conductors. Pure solidionic compounds are conductors, because they are found in solid state, but molten ionic compounds are conductors or non-conductors), because ionic component show property of metal.Pure molecular compounds are generally (conductors or non-conductors). A concentrated aqueous solution of a strong acid such as HCl is a (conductor ornon-conductor), because. As the concentration of the HCl solution decreases, the conductance increases), because Mixtures of metalsare non-conductors), because it doesn't show property of metal.
Metals and molten ionic substances and electrolyte solutions, conduct electricity.
The words that fill in the blanks are;
Metals are conductors because of the presence of free electrons in the metal which are available.
In an ionic solid, the ions are the charge carriers and they are bound up in the lattice making the ionic solid not to be a conductor.
In the molten state, the crystal collapses and the ions are released. Hence, the molten ionic substance is a conductor.
Solutions of electrolytes such as HCl conducts electricity due to mobile ions which are charge carriers in solution. As the concentration of the solution decreases, the number of ions in solution decreases and the conductivity of the solution decreases accordingly.
Mixtures of metals called alloys are still conductors of electricity due to the presence of free electrons.
