The characteristic of metal atoms help explain why valence electrons in a metal are delocalized is C. Metal atoms are large and have low electronegativities.
In chemistry, localized electrons and delocalized electrons are terms that tells about chemical structures of chemical compounds. Delocalized electrons are nonbonding electrons that occur as electron clouds above and below the molecule.
The electronegativity of an element is the relative tendency of its atom to attract electrons towards itself when it is bounded to the atom of another elements.
