Potassium electronic structure

Phenylmercury derivatives of 3-aminomethylene-l-methyloxindols have also been investigated (79KGS65). For studies of the effect of substituents on the electronic structure of silver and potassium salts of 3-(aryl)imi-nooxindole see 76MI2. The keto-enol and imino-enamine tautomerism of compounds of type 127 (with 128 and 129) has been investigated (85KGS921). 

Figure 6.25. Valence band photoemission spectra of 1 ML Ceo on a Ag(lOO) surface as a function of potassium doping. Also shown are the spectra of the clean Ag(lOO) surface and of a Ceo multilayer (bottom). All binding energies are referred to the L f of polycrystalline silver.

At first glance, the standard potentials listed in Table 1 are largely nondescript. All are quite similar, with the possible exception of the sodium couple, which might appear to be anomalously positive. These values are qualitatively consistent with the simple picture that develops upon consideration of the electronic structures of the metals and their oxidized monovalent cations. Each of the metals exhibits an electronic structure that can be symbolized by (noble gas) s, where the principal quantum number (n) ranges from 2 < < 7. For example, the electronic structure for potassium is [Ar]4s, that is, ls 2s 2p 3s 3p 4sk Each of the alkali metals can easily lose one electron to give a stable monovalent metal cation that is isoelectronic with the noble gas... 

The Ozonide Ion.—The red crystalline substance potassium ozonide, KO3, is obtained by recrystallizing from liquid ammonia the product of reaction of ozone and potassium hydroxide.47 The corresponding ozonides NaO and CsO hasre been shown48 to have magnetic susceptibility corresponding to the presence of the OjT ion with one odd electron. The electronic structure of the ozonide ion is... 

J. W. Briihl s observations on the refractive indices agreed with the formula H0.0.N=0 but R. Lowenherz s values for ethyl, propyl, isobutyl, and amyl nitrates agree better with the quinquevalent nitrogen atom. H. E. Armstrong and F. P. Worley made some observations on the constitution of nitric acid—vide sulphuric acid. H. Burgarth, H. Remy, and H. Henstock discussed the electronic structure and from observations on the absorption spectra of sodium and potassium nitrates in different solvents, G. Scheibe inferred that the nitrate ion is dipolar, and that the electronic structure is such that the first of the following forms exists in equilibrium with small proportion of the second ...

Cyclooctatetraene readily reacts with potassium metal to form a dianion. Discuss the electronic structure and geometry of this dianion and explain why it is formed so readily. 

From our knowledge of the electronic structure of their atoms, we can predict a reasonable formula for the simplest molecule that might be formed by a metal combined with a nonmetal. For example, we can recognize the univalence of both potassium and chlorine atoms and predict that the simplest molecule will have the molecular formula, KCl. However, a single bond in such a molecule would use only one electron from each atom, leaving unused both vacant orbitals on the potassium and electron pairs on the chlorine.
