PART IVSUPERCONDUCTIVITYNonstoichiometric CompoundsThe Law of Definite Proportions is one of the basic laws of chemistry and its validity has been demonstrated in many compounds. Yet metallic compounds composed of oxides, sulfides, etc., are nonstoichiometric. Why? These solid compounds have some other basis of formulation other than the simple law of proportions. High Tc superconducting materials are in the nonstoichometric category. An explanation of nonstoichiometric metallic compounds can be made with the help of the circular periodic table/model. An example: Zinc (30) has an oxidation state of +2, and generally forms compounds in this second oxidation state. This brings the cation back to the positive pole. What happens to copper (I) cation, and (II) cation is different. Copper (29), is against the polarity line. The first ionization state of copper is also against the polarity line, but with the electron missing. The second ionization of copper (II) is impacted by several factors at this point: (A) Evidence of energy differentials between the right hemisphere positive energy and left hemisphere negative energy field can be ascertained from the spin states. Positive spin states have more energy than negative spin states. (B) The law of alternating multiplicities pertains to ions as well as electrons. (C) The positive polarity barrier causes copper ionization states to move contrary to normal cation ionization states. (D) The sliding of S shell electrons. Nickel (28), has two outer S shell electrons in its configuration. Yet copper, the next element has a single S shell electron in its configuration. Where did the second S shell electron disappear? This accounting for shifting of electrons in the S shells is a distinctive characteristic of the Circular Model of the Atom. Thus the copper (II) ion moves over to the D10 position within Group II elements. (E) Antiferromagnetism boundary originates along positive pole elements in group I. As a result of these structures, (polarity, boundaries, fields, rays, multiplicities, spin, etc.) within each neutral atom, there are areas that are more positive and areas that are more negative. Each element, in forming nonstoichiometric metallic compounds is influenced by the opposite cation or anion and seeks to adjust proportions to produce a neutral compound. |
