Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn't actually much to work out. But when elements lo...
A PRECISE measure of the charge on an atom in a molecule is provided by calculating the number of electrons within a sphere of covalent radius using molecular wavefunctions. The results for alkyl substitution suggest that the simple qualitative ideas of the inductive effect may be less simple ...

The original SMILES has six charged atoms (three N and three O), while the final molecule has only two of each. Let's compare them. Here is the original molecule. And here is the final one. This also is obviously wrong. There are neutral nitrogens forming five bonds. ...
. We achieved this by adapting electrophilic addition to alkenes as the basis for a general, predictable and highly selective strategy termed ‘charge relocation’—a synthetic logic in which incipient or localized charge at a given atom relocates to a defined position through a series of hydride...

Space-charge layers are frequently believed responsible for the large resistance of different interfaces in all-solid-state Li batteries. However, such propositions are based on the presumed existence of a Li-deficient space-charge layer with insufficien
