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.

Sulfates (salts with the SO₄^2-) are frequently used in industry and biologically.

A commonly used sulfate is sodium lauryl ether sulfate found in shampoo, toothpaste, etc.

For example, MgSO₄ is also known as Epsom Salts.

There are 32 valence electrons available for the Lewis structure for SO₄^2-.

Video: Drawing the Lewis Structure for SO₄^2-

It is helpful if you:

• Try to draw the SO₄^2-Lewis structure before watching the video.
• Watch the video and see if you missed any steps or information.
• For more help, watch this general tutorial on drawing Lewis Structures for compounds like the Sulfate ion.
