particle nature
In solid-state, representation of a metallic solid as a container filled with a gas composed of free electrons (i.e., those responsible for high electrical and thermal conductivity).
The free electrons, considered identical to the outermost, or valence, electrons of free metal atoms, are presumed to be moving independently of one another throughout the entire crystal.
The particle nature is the emission of free electrons from a metal surface when the light is shone on it, it is called the photoemission or the photoelectric effect.
The outermost electrons of the constituent atom of the metal are weakly bound with the atoms. Hence these electrons get separated from their atoms and move freely inside the substance and are called free electrons.
