VSEPR THEORY POP FLASHCARD

Front

What is VSEPR Theory?

Back

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

Front

What determines the shape of a molecule according to VSEPR Theory?

Back

The shape of a molecule is determined by the number of bonding pairs and lone pairs of electrons around the central atom.

Front

What is a lone pair?

Back

A lone pair is a pair of non-bonding electrons located on the central atom.
