Lewis Dot Structures - Missouri S&T

This theory is known as Valence Shell Electron Pair Repulsion Theory or VSEPR theory. The most common molecular shapes are shown in the table below. Bonding orbitals form when the valence orbitals on two atoms share a pair of electrons. The resulting orbital is called a “localized bonding orbital.” It is called “localized” because the ...

La forma delle molecole - Zanichelli

La teoria VSEPR (Valence Shell Electron-Pair Repulsion, teoria della repulsio-ne delle coppie di elettroni del “guscio” di valenza) consente di ricavare la geometria, ossia la forma delle molecole, a partire dalle rappresentazioni delle formule di struttura di Lewis, partendo dal presupposto che le coppie
