網頁1 Answer. An s-orbital is basically a pretty perfect sphere around the nucleus. A sphere transforms upon itself no matter which element of symmetry you use. Thus, it cannot be the basis of any kind of chirality or other asymmetry. 網頁2024年1月15日 · The stereochemical activity of lone-pair electrons plays a critical role in materials properties, e.g. low thermal conductivity in PbCuSbS3 [9], selectivity in the Pb (II) protein binding [10] and a phase transition in (2-MIm)SbI 4 [11].
