Aluminum metal is produced by heating aluminum oxide, Al₂O3(s), and other substances to almost 1000 °C until the mixture melts. Molten aluminum oxide is an excellent conductor. An electric current passed through liquid aluminum oxide can provide the electrons needed to convert the aluminum ions to neutral metal atoms. Explain the following

3. Aluminum metal is produced by heating aluminum
oxide, Al₂O3(s), and other substances to almost
1000 °C until the mixture melts. Molten aluminum
oxide is an excellent conductor. An electric current
passed through liquid aluminum oxide can provide
the electrons needed to convert the aluminum
ions to neutral metal atoms. Explain the following
properties of aluminum oxide in terms of ionic
bonding: IK/U
(a) its high electrical conductivity when molten
(b) its high melting point
