Of , and , none has an electric dipole moment, but one does have a magnetic dipole moment, which one, and why?
(Refer to figure 10.10)
Here, O2 has a dipole moment.

The accompanying diagrams represent the three lowest energy wave functions for three "atoms." As in all truly molecular states we consider, these states are shared among the atoms. At such large atomic separation, however, the energies are practically equal, so anelectron would be just as happy occupying any combination.
(a) Identify algebraic combinations of the states (for instance, 5+11/2+11/2 ) that would place the electron in each of the three atoms.
(b) Were the atoms closer together, the energies of states 1.11, and III would spread out and an electron would occupy the lowest energy one. Rank them in order of increasing energy as the atoms draw closer together. Explain your reasoning.
The bond length of themolecule is 0.11nm, and its effect the spring constant is .
(a) From the size other energy jumps for rotation and vibration, determine whether either of these modes of energy storage should be active at 300K .
(b) According to the equipartition theorem, the heat capacity of a diatomic molecule storing energy in rotations but not vibrations should be(3 translational +2rotational degrees of freedom). If it is also storing energy in vibrations. it should be(adding 2 vibrational degrees). Nitrogen's molar heat capacity is 20.8J/mol.K at 300K. Does this agree with your findings in part (a)?
The vertices of a tetrahedron are four vertices of a cube symmetrically chosen so that no two are adjacent. Show that the angle between the vertices of a tetrahedron is .
The resistivity of the silver is at room temperature of (300 K), while that of silicon is about
(a) Show that this disparity follows, at least to a rough order of magnitude from the approximate 1 eV band gap in silicon.
(b) What would you expect for the room temperature resistivity of diamond, which has a band gap of about 5 eV.
In a buckyball, three of the bonds around each hexagon are so called double-bonds. They result from adjacent atoms sharing a state that does not participate in the sp2 bonding. Which state is it, and what is this extra bond σ-bond or a π-bond? Explain.
