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