An attempt to reconcile conflicting measurements of the bond strengths in the xenon fluorides. Presents the valence-shell electron-pair repulsion (VSEPR) theory of directed valency and its use to determine molecular shapes, bond angles, and bond lengths. As electron pairs are negatively charged and will … Action of organometallic reagents on chiral bifunctional silanes. Stereochemistry and the choice between alternative descriptions of oxidation states.

The premise of VSEPR is that the valence electronpairs surrounding an atom tend to repel each other and will, therefore, adopt an arrangement that minimizes this repulsion. L. S. Bartell, R. M. Gavin, H. Bradford Thompson, C. L. Chernick. S. Bauermeister, T. A. Modro, P. K. Psotta, P. H. Van Rooyen. and XeF

Through handling, balloons acquire a slight surface electrostatic charge that results in the adoption of roughly the same geometries when they are tied together at their stems as the corresponding number of electron pairs.
