Question

What does the sea of electrons contain ?​

Answer 1

Answer:

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. ... Metals are shiny.

Answer 2

By simulating metals as a mixture of atomic cores (atomic cores = positive nuclei + inner shell of electrons) and valence electrons, Paul Drüde developed the "sea of electrons" metallic bonding theory.

The Electron Sea:

• Positive metal ions are surrounded by a body of delocalized electrons in metallic bonds.
• It is a metal bond of its own. The electrons float around the atoms when metals are present.
• In their outermost energy shells, the majority of metals contain a very small number of electrons, and some have empty outer electron orbitals.
• It is known as the electron sea model for this reason.
• Solid metal structures also include delocalized electrons.
• A "sea" of delocalized electrons surrounds aligned positive ions (cations) in a metallic structure.
• This results in qualities like conductivity since the electrons are free to move about the structure.
• The ocean of electrons moves about.
• Electrons will migrate carrying an electrical current if a potential difference is applied across a metal piece.
• Because of this, metals are effective electrical conductors.

Electrons that have "delocalized," or more simply, don't belong to or orbit any one atom, are referred to as a "sea" of electrons. Metal fuses with the metal in this manner. Metal atoms shed their outer shell electrons and combine to form positive ions, which are held together by the liberated electrons.
