Question “Band theory is an extension of molecular orbital theory. According to band theory, atomic orbitals between…”
Band theory is an extension of molecular orbital theory. According to band theory, atomic orbitals between atoms in a sample form a nearly continuous band of molecular orbitals. In a metal, the bottom half of the band is composed of bonding molecular orbitals and the top half of the band Is composed of anti-bonding molecular orbitals. Transition metals from the 4th period have a band of molecular orbitals formed from a composite of 4s and 3d orbitals. Metallic properties, including melting point, ductility, and conductivity, can be predicted by the degree to which the bonding and anti-bonding portions of the band are filled. Match the diagram below to the transition metal it represents.
