Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

What is the main principle of VSEPR theory?

Back

Molecules adjust their shapes to keep pairs of valence electrons as far apart as possible.

Front

What is hybridization in chemistry?

Back

A process in which atomic orbitals mix to form new, identical hybrid orbitals.

Front

What does the VSEPR model help predict?
