Which statement correctly explains why metals conduct electricity?

• Metals contain sea of delocalised mobile valence electrons which can move throughout the structure

• Metals contain ions which are free to move throughout the structure

• Metals contain an electrical current

• Metals are magnetic

Which statement correctly explains why ionic compounds conduct electricity as a LIQUID?

• Ionic compounds contain delocalised valence electrons which can move throughout the structure

• Ions are free to move

• Ions are fixed in position

• Ionic compounds contain an electrical current
