What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

What is the molecular geometry of a molecule with 3 bonding pairs and no lone pairs?

Back

Trigonal planar.

Front

What is the significance of lone pairs in determining molecular shape?

Back

Lone pairs occupy space and can affect the angles between bonding pairs, altering the molecular geometry.

What is the 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 electron pairs.
