Bismuth valence
WebBismuth compoundsare compounds containing the element bismuth(Bi). Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenicand antimony, although they are less toxic than derivatives of those lighter elements.

WebFeb 1, 1999 · Bi 1−x Y x O 1.5+δ (x ∼ 0.4, 0 < δ < 0.16) is a recently identified bismuth mixed-valence oxide. To provide clear evidence of the valence state of the Bi ion, Bi L 3 X-ray absorption near edge structure (XANES) spectra were measured in polycrystalline materials. These spectra were found to be similar to that of Bi 2 O 3 as a reference to B … WebMar 1, 2007 · The only significant difference between inner and terminal bismuth atoms, visible in the density of states (DOS), is at the bottom of the valence bands, with the energy lower than about −8.2 eV. In this region of the DOS only the contributions from terminal bismuth atoms and halogens are significant. Download : Download full-size image; Fig. 2.
