What determines the shape of a molecule?

Back

The shape of a molecule is determined by the number of bonds and lone pairs of electrons around the central atom, as described by the VSEPR (Valence Shell Electron Pair Repulsion) theory.

What is VSEPR theory?

Back

VSEPR theory (Valence Shell Electron Pair Repulsion) is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

Front

What is a lone pair?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.
