BCl_3 For this structure, how many equivalent resonance structures exist? How many electrons exist in the valence of the central atom? Which of the following elements can only have a single bond in a Lewis structure? a. C b. O c. P d. F In the Lewis structure for SiBr4, Si ha...
Magnetosomes were also found in some single-cell eukaryotes, such asPhytoflagellataandAnisonema(Euglenophyceae). Their cells contain thousands of magnetite crystals, which are very similar to those in magnetotactic bacteria. However, the origin of these magnetosome-like structures is still unknown....
This is a clear definition, even though the results depend on the definition and optimi- zation of the orbitals used to define the individual resonance structures. Thus, VB theory does offer a definition of charge transfer, so that, with sufficient definition of the exact calcu- lational ...
