Describe how the sea-of-electrons model is used to explain the physical properties of metals.

Answer:

The atoms of a metal are submerged into a sea of delocalized valence electrons.
Malleable - the metal atoms are free to move, as they are not bonded to anything.
Shiny - the delocalized valence electrons become excited and emit energy, which we perceive as light.
