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.

The characteristics of metallic bonds explain a number of the unique properties of metals: Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current. Metals are ductile and malleable because local bonds can be easily broken and reformed.

Answer 2

The electron sea model explains many of the physical properties of metals. They are good electrical conductors because the electrons flow freely in them. They are malleable because of the drifting electrons and because the cations slide easily past each other.

bonding the electron see model in this model the valence electrons of the metal scattered delocalized and. they do not remain attached to any particular atom but forms a sea of electrons ...

In metals the outer electrons are delocalized and can move around within the metal freely. If the energy needed to go out of the metal is 1eV, the energy needed to move within metal is one millionth of 1eV. Also, there are large number of electrons moving; each atom contributes one electron or more. This is visualized as sea of electrons. The ionized atoms are immobile and fixed in a structure. This model is used to understand conductivity and other electrical properties of metals.
