Learning objective
Explain the quantum nature of the chemical bond using the hydrogen molecular ion and the hydrogen molecule.
Learn to distinguish covalent and ionic bonds and to estimate the energy of an ionic bond.
Master the terms of diatomic molecules and the calculation of rotational and vibrational energy levels.
Relate the structure of solids to the types of bonding.
Expected outcomes
Can show the binding energy and equilibrium distance on the potential curve U(R).
Explains the role of bonding and antibonding orbitals and of the exchange interaction.
Can calculate the moment of inertia, the rotational constant B, the vibrational quantum ħω and the force constant.
Distinguishes ionic, covalent, metallic and molecular crystals and finds the lattice constant from the density.
