Front

Define VSEPR Theory.

Back

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

Front

What does the term 'bonding pair' refer to?

Back

A pair of electrons that are shared between two atoms to form a covalent bond.

Front

What is the molecular shape of CO₂?

Back

Linear.

Front

How does a lone pair affect molecular geometry?

Back

Lone pairs occupy space and repel bonding pairs, altering the shape of the molecule.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?
