Name one ionic compound that contains a polyatomic cation and a polyatomic anion (see Table 2.3).
MO’s in one-dimensional arrays of like orbitals There will be as many MO’s as orbitals in the array. Every molecular orbital is characterized by a specific pattern of nodes, The lowest energy orbital will have zero nodes, the next highest will have one node, the next two, etc. The highest energy molecular orbital will have n-1 nodes, where n is the number of atomic orbitals involved. When symmetrical placement of a node causes it to fall on an atom, then that atom does not contribute to the molecular orbital. Bonding and electronic structure of metals and other solids Any successful model for the bonding in solids must be able to explain - good thermal and electrical conductivity of metals - Origin of semiconducting and insulating behavior Molecular Orbital theory can be
