Why metal is a good THERMAL conductor but plastic is a worse conductor than metal? Is it also due to the delocalised electrons of the metal?plz explain it.

    ya!its due to the delocalised electrons,plz bear in mind that,do not write free electrons during exams,or marks will be deducted!u must write DELOCALIZED ELECTRONS.

    giant metallic structure---delocalized electrons

    giant ionic structure-----mobile ions

    giant covalent-----delocalized

    simple molecular struct.----absence of mobile ions
