Question

Electron Sea Model or Electron Gas Model explain in very easy manner

Answer 1

The electron sea model is a model of metallic bonding in which cations are considered to be fixed points within a mobile 'sea' of electrons.

Free-electron model of metals, in solid-state physics, 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). ... It did not, for example, take into account the interaction of free electrons with the metal ions.
