The atoms of the metal will be taking the outer electrons of the metal atoms, the result is that there are no molecules that move so Cera-., it is a good heat insulation.
The outermost electrons of metal atoms to renounce to the metal atoms results were not moving so ceramide molecules - Mick. It is a good thermal insulator.
The atoms of the metal are taking the outer electrons ultimately to the atoms of the metal the result is no molecular movement so sera - Mick is a good thermal insulation.
