Question

electrons that are free to move in metals
oxidation number
chemical bond
delocalized electrons
salts

Explanation:

Delocalized electrons are electrons in a molecule, ion, or solid metal that are not associated with a single atom or a covalent bond. In metals, the delocalized electrons form a "sea" of electrons that can move freely throughout the metal lattice. This property is responsible for the electrical conductivity and thermal conductivity of metals. Oxidation number refers to the charge an atom would have if all bonds were ionic. A chemical bond is an attraction between atoms that allows the formation of chemical substances. Salts are ionic compounds formed from the neutralization reaction of an acid and a base.

Answer:

delocalized electrons
