Question

which is most likely the result of millions of metal atoms crowding together so that molecular orbitals become combined? the loss of metallic properties the formation of bands in a crystal the loss of valence electrons to other atoms the formation of localized valence electrons

Explanation:

When millions of metal atoms crowd together, according to the band - theory in solid - state physics, molecular orbitals combine to form energy bands in a crystal. Metallic properties are not lost; valence electrons are delocalized rather than lost to other atoms or localized.

Answer:

the formation of bands in a crystal
