WebSep 7, 2024 · According to the band theory, semiconductors will actually act as insulators at absolute zero. Above this temperature and yet still staying below the melting point of the solid, the metal would act as a semiconductor. Semiconductors are classified by the fully occupied valence band and unoccupied conduction band. WebAug 11, 2024 · Metallic bond. For the ion binding of NaCl the energy per molecule is calculated by: E = cohesive energy (NaCl) – ionization energy (Na) + electron affinity (Cl) The interaction in a covalent bond depends on the relative spin orientations of the electrons constituting the bond.
