Recently we have extended the study to bis(thiophosphinyl)disulfanes and bis(thiophosphoryl)disulfanes (S PR , tetraalkyl thiuram disulfides [R NC(S)S] (DTC) , dibenzothiazolyl disulfide (C H NSCS) and Lawesson’s reagent. The unexpected reactivity of cyclopentadienylchromium tricarbonyl in extensive cleavage of C S and M X bonds (X=S, P, N and C) in the derived complexes has resulted in many classes of organometallic complexes and novel polynuclear compounds, some of which are illustrated in the Chart below.

CHEMISTRY - THE PERIODIC TABLE - ELECTRONIC CONFIGURATION - BONDING David Harrison School of Science and Technology Athrofa Addysg Uwch Gogledd Ddwyrain Cymru North East Wales Institute of Higher Education Wrexham, NORTH WALES The Periodic Table The Periodic Table is much more than just a list elements or an aide-memoir. The great Russian chemist Dmitri Mendeleyev (1834-1907) proposed the idea in 1870 although in 1864 the English chemist John Newlands (1837-1898) noticed repetitions in properties when the elements were placed in order of weight, his "law of octaves", though this only led to his ridicule. You can read some of Newland's letters to the Editor of the Chemical News at http://web.lemoyne.edu/~giunta/newlands.html Johann Wolfgang Dobereiner 1 H 2 Li 3 Be 4 B 5 C 6 N 7 O 8 F 9 Na 10 Mg 11 Al 12 Si 13 P 14 S 15 Cl 16 K 17 Ca 19 Ti 20 V 21 Cr 22 Mn 23 Fe 24 Co 25 Ni 26 Cu 27 Zn 30 As 31 Se 32 Br Figure 1. Part of the Mendeleyev Periodic Table. Mendeleyev noticed that there were obvious gaps ( ) and one of the successes of his periodic table was that it predicted the likely existence of missing elements that were eventually discovered: 18 scandium (1879), 28 gallium (1875) and 29 germanium (1886). At the turn of the century a whole new family of elements helium, neon, argon, krypton and xenon were discovered and the Mendeleyev Table was modified to include the new elements in a new column at the right hand side. The modern Periodic Table permits the chemist to rationalize atomic structure, chemical behaviour, formulae, the structure and bonding in compounds etc., it is not simply a list of elements. The modern form of the Periodic Table owes its existence not only to Mendeleyev but to

Materials Chemistry Part II This overview is geared towards MSE 204 Prelim II. It covers multi-electron systems and group theory and its application to multi-nuclear systems. Keep in mind throughout the overview that almost everything in Quantum Chemistry is just an approximation. Key Concepts from Last Section The standard eigenvalue problem for the hydrogenlike system is set up as follows: The eigenfunction comes in the following form: and the Hamiltonian operator for Hydrogen is as follows: The energy, or the eigenvalue from the Hamiltonian, is as follows: where: and z is the number of protons and n is the 1st quantum number. Multi-Electron Systems Let's for now use the simplest case example of the multi-electron system, the H ion. Because of the fact that there is perturbation, the new Hamiltonian operator comes in the following form: where the Hamiltonian for the nonperturbed system is a sum of the Hamiltonians for the component particles as follows: where: and the perturbation problem is as follows: The perturbation problem is to be neglected.

CHEMISTRY 1b, SPRING, 2000 SOLUTIONS TO THE FIRST MIDTERM EXAMINATION 1) Consider the reaction Cu (aq) + 2 Cl a) Sketch an electrochemical cell based on the reaction. Label each electrode and include the half reactions that occur at each electrode. The anode is a silver electrode electrocoated with solid silver chloride. It is dipped in an aqueous solution containing chloride ion. The half-reaction at the anode is Ag(s) + Cl The cathode is a copper electrode that dips in an aqueous solution containing Cu(II). The half-reation at the cathode is Cu The two solutions are physically separated, e.g. stored in separate beakers, but are connected by a salt bridge that provides electrical continuity. The two electrodes are connected by a wiring that has a resistive load in series. D Cu Cl D c) A cell based on the above reaction is assembled in which the concentration of Cu+2 is 0.20 M and the concentration of Cl E = 0.12 V - ((0.05916 V)/2))log d) What conditions must be satisfied in order to solve part c? In order to relate a change in thermodynamic state functions to the electrical work, the cell must be run reversibly (i.e. very high resistive load) AND at constant temperature and pressure. The cell is not run under standard conditions; note that the concentrations of the chloride and copper(II) species are not 1 M.

Click here to go to a "printable" version of this assignment that can be given to students or slightly modified to give to students. Below is a second semester project that was given to Bailey's Chemistry Students. They were told that they could put it together and present it in any way they wanted, as long as it made sense. Some chose to create web pages for at least a portion of it. Others produced video tapes that were rather clever, and many others simply produce periodic tables. Some students come up with some interesting configurations that, at first glance, just look "weird." However, upon interviewing the students about the logic behind the constuction of their tables, it is often quite apparent that their table makes sense. Suppose that in another universe there is a completely different set of elements from the ones we know. The inhabitants have discovered a total of 35 different elements and have assigned the letters A though Z to represent the first 26 elements in order of increasing atomic number. For elements 27 through 35, the alphabet is started over again with two-letter representation, one uppercase and the other lowercase (ie #27=Aa). The inhabitants of this universe have found that the following two groups of elements closely resemble one another in their chemical properties.

Magnetic Fields and Forces Our brief mention of the changing electric and magnetic fields in radio and light waves has already led the discerning reader to conclude that electric fields and magnetic fields are closely related. In fact, much of what we have learned about the electric field applies to magnetic fields as well: both exist in the presence of sources the force on a test object is given by the product of the test object and the field; both depend on 1 / r , and both include a dimensionful constant of proportionality. But whereas the electric field is caused by the presence of electric charges , the source of the magnetic field is a current element I l the product of a current and its length. And while the direction of the electric field is radial relative to the source, the direction of the magnetic field is a three-dimensional function of the current direction and the field point called the cross product We have already discussed the x and y components of forces in two dimensions, on a plane. In three dimensions, there is a z component as well which is perpendicular to the x-y plane. With the usual orientation of the x-y plane: the positive z direction points out of the page towards you and the negative z direction points into the page away from you.

Quantum Numbers and the Periodic Table We have seen that the energies of bound electrons are quantized , and have labelled the energy levels with an integer n. We mentioned that the orbits are not necessarily circular, nor are they planar. Instead, they are three dimensional, so that instead of circular, we have spherical, and instead of elliptical, we have ellipsoidal. In fact, the energy of an atomic electron depends not only on n, but on angular momentum, orientation, and spin as well. These effects are not predicted by the Bohr model, but derive from the more advanced (and complicated!) Schrodinger and Dirac Equations. We therefore "label" an atomic electron by four "quantum numbers": n = 1, 2, 3, ...., denoting energy; l = 0, 1, ..., n-1, denoting angular momentum m = - l l , denoting orientation (the "magnetic quantum number"), s = -1/2, 1/2, denoting spin (m s is also used in place of s). The set of four numbers (n, l , m,s) identifies the "quantum state" of the electron. Chemists use letters in place of numbers for l (s, p, d, f, etc.), and so an n=3
