Rare gas configuration

Halide ions have lower orbitals filled in a rare gas configuration. Their reaction rates with eh are expected to be small, which is verified experimentally. I, I , and CIO-, however, react with e, at near diffusion-controlled rates. [Pg.184]

This simple band model predicts that an alloying metal with 10 - - z valence electrons outside a filled p shell (rare gas configuration) is expected to decrease the magnetization of nickel by approximately z Bohr magnetons per solute atom pb)- As illustrated in... [Pg.616]

Formation Constants pk( = —log K) for Complexes of Triphosphates with Ions not Having the Rare Gas Configuration... [Pg.34]

Ions which do not have a rare gas configuration appear not to fit into this rule. They are much more firmly bound than the alkali and alkaline earth cations. A dependence on radius is not observed and for Hg(I) the binding is stronger with the diphosphate anion than with triphosphate 366). (See, also the binding of cations by highmolccular polyphosphates, Section IV,E,/,d.) For the analysis and determination of triphosphates, see Section VII,B. [Pg.34]

In the following groups some of the valency electrons are d electrons. In chemical processes the s and p electrons of the outer shell will be removed first, but the d electrons can also be removed. The maximum valency is reached when all electrons in the outer shell plus the d electrons are given off, an ion with rare-gas configuration being formed. In addition to this highest valency, all kinds of lower valencies are possible for titanium and vanadium the chlorides are... [Pg.45]

The inner coordination sphere of the dimer is shown in Figure 5. By the normal rules of electron counting, the rare-gas configuration is obeyed at platinum if a Pt=Pt double bond is invoked. Yet the Pt-Pt distance of 2.765(1)A is a normal or slightly long, single bond. One thus wonders if the compound might be a... [Pg.39]

The rr-allyliron tricarbonyl cations are unusual because the iron atom is two electrons short of the next rare gas configuration. [Pg.146]

Electronic configurations of ions are obtained in much the same way as those of elements. The fluorine atom has nine electrons, so the F ion (with ten electrons) would have the same configuration as Ne gas. Similarly, the sulfide ion (S2 ) would have the argon structure. All monatomic negative ions in ordinary systems have rare gas configurations (except for a negative ion of rhenium which has been reported). [Pg.21]

The atoms of Ti, Zr, and Hf have two s electrons and two inner d electrons beyond rare gas configurations. All four of these electrons may be... [Pg.438]

Hexacoordinate species (C = 6) with the rare gas configuration E = 18) are particularly favored. Therefore, in the CEQ-msitrix the row corresponding to C = 6 and the column corresponding to F = 18 are outlined in double lines. In the rhenium C /Q-matrix (Table I), as well as the other Ci/Q-matrices given in this paper (Tables II to VII), the complex types are concentrated along the C = 6 row and the = 18 column. [Pg.208]

Ideally an ACQ matrix is three-dimensional with the dimensions corresponding to atomic number (A)j coordination number (C), and ionic charge (Q). The electronic configuration (E) is constant for the listed series of complexes—generally the favored rare gas configuration E = 18. [Pg.219]

How many bonding and how many nonbonding pairs of electrons are in one molecule of ethylene glycol, the compound used as antifreeze in automobile radiators Does every atom in the molecule have a rare gas configuration ... [Pg.270]

The four orbitals of the M shell of the aluminum atom are occupied by only three electrons (3s2,3p), which give rise to the coordinatively unsaturated character of the element (sp2 hybrid). For organoaluminum compounds (Lewis acids) the conversion to the stable rare gas configuration can... [Pg.269]

The various atoms in a compound have the tendency to give up, or take on, or share electrons in such a way as to be surrounded by a shell of eight electrons (rare gas configuration). When electrons are shared, they may be shared equally, as in Hg and unequally, as in NaCl, so that one has aU possible... [Pg.192]
