Metals have low ionization energies and readily share their or outer electrons with each other to form an electron . These electrons are or shared among all the atoms that are bonded together and can therefore move freely throughout the metal structure.

Valence, Sea, Delocalized (Pooled) are the correct answer of this question.

Explanation:

Valence usually reflects the amount of electrons available to fill an atom's topmost shell.An molecule's valence is the amount of protons which can interact with or substitute (explicitly or implicitly) one of the molecule's atoms.Its electron marine model is a magnetic attachment method in which cations are assumed to be quantum superpositions within a rotating particle' sea.'Delocalization occurs as orbital angular momentum is distributed through more than one atom.

For example:-bonding electrons can be distributed among many bonded        atoms.
