Chlorine electrons

Here the Tj = (m, x + i2 y + WI3 )a are (he positions of the ions. We see immediately that there are as many values of k as there are chlorine ions these correspond to the conservation of chlorine electron states. We also see that the wave Inunctions for states of different k are orthogonal to each other. Values for k run almost continuously over a cubic region of wave number space, — nja < <... 

Aromatic chlorination. This reagent PhS(=NS02CFi)2Cl chlorinates electron-deficient arenes at room temperature. 

Here the = (mi x + m2 y + m3 z)a are the positions of the ions. We see immediately that there are as many values of k as there are chlorine ions these correspond to the conservation of chlorine electron states. We also see that the wave functions for states of different k are orthogonal to each other. Values for k run almost continuously over a cubic region of wave number space, — n/a < k < nia, — nja Brillouin Zone, here cubic, depends upon the crystal structure.) For a macroscopic crystal the Af, are very large, and the change in wave number for unit change in is very tiny. Eq. (24) is an exact solution of Eq. (2-2) however, we will show it for only the simplest approximation, namely, for the assumption that the s,) are sufficiently localized that we can neglect the matrix element Hji = (sj H s,) unless (1) two states in question are the same (/ = j) or... 

As discussed previously, U.S. Patents 3,989,881 and 4,125,532, contain a large number of magnesium/titanium/chlorine/electron donor complexes that are suitable candidates for the preparation of a wide variety of high-activity catalysts for ethylene polymerization catalysts supported on silica, using the physical impregnation method. In this method, the Mg/Ti/Cl/ electron donor complexes are prepared in the particular electron donor solvent and then this solution is added to silica, after which the electron donor solvent is evaporated to cause the solid complex to be deposited into the silica pore structure. The silica only acts as a carrier of the Mg/Ti/elec-tron donor complex, which becomes the active species once the complex is reacted with an alumimun alkyl. 

As you saw on the last page, a sodium atom can lose one electron, and a chlorine atom can gain one, to obtain full outer shells. So, when a sodium atom and a chlorine atom react together, the sodium atom loses its electron to the chlorine atom, and two ions are formed. Here, sodium electrons are shown as and chlorine electrons as x, but remember that all electrons are exactly the same ... 

A FIGURE 4.24 Oxidation-Reduction without Oxygen When sodium reacts with chlorine, electrons transfer from the sodium to the chlorine, resulting in the formation of sodium chloride. In this redox reaction, sodium is oxidized and chlorine is reduced.
