Commonly Tested Lewis Structures

We draw Lewis Structures to predict:

-the shape of a molecule.

-the reactivity of a molecule and how it might interact with other molecules.

-the physical properties of a molecule such as boiling point, surface tension, etc.

SO₃ is the primary contributer to acid rain in the atomsphere. It is a form of pollution.

SO₃ is named Sulfur Trioxide.

There are 32 valence electrons available for the Lewis structure for SO₃.

Be sure to check the formal charges for the Lewis structure for SO₃.
