Lewis Dot Structure and Geometry Review

Front

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.

Front

What does the term 'covalent bond' mean?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

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

Back

Tetrahedral.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.

Front

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

Back

Trigonal planar.

Front

What is the shape of a molecule with three bonding pairs and one lone pair?

Back

Trigonal pyramidal.

Front

In a Lewis Dot Structure, what do dots represent?

Back

Dots represent valence electrons.

Front

How do you determine the shape of a molecule?

Back

The shape of a molecule can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory.

Front

What is the VSEPR theory?

Back

VSEPR theory states that electron pairs around a central atom will arrange themselves to minimize repulsion, leading to specific molecular shapes.

What is the molecular shape of CO2?

Back

Linear.
