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.

Ammonia (NH₃) is a commonly tested Lewis structure due to it's widespread use in agriculture as a fertilizer. It also is a good example of a molecule with a trigonal prymidal molecular geometry.

There are 8 valence electrons available for the Lewis structure for NH₃.

Video: Drawing the Lewis Structure for NH₃

It is helpful if you:

• Try to draw the NH₃ 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 Ammonia molecule.
