Why are metals good conductors of electricity?
Show answer
Because the delocalised electrons in the metal carry electrical charge through the metal.
Why are metals good conductors of thermal energy?
Show answer
Because energy is transferred through the metal by the delocalised electrons.
Metals conduct electricity because ? electrons carry electrical charge through the metal.
Show answer
delocalised
In a metal, delocalised electrons carry ? through the metal, making it a good electrical conductor.
Show answer
electrical charge
Which particles in a metal carry electrical charge through it?
Show answer
Delocalised electrons.
Which particles transfer thermal energy through a metal?
Show answer
Delocalised electrons.
Which single feature of metallic bonding explains both electrical and thermal conductivity in metals?
Show answer
The delocalised electrons: they carry electrical charge and transfer thermal energy through the metal.
