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.

Drawing the Lewis Structure for NO3- (Nitrate Ion)

Nitrates (salts with NO3-) are frequently used in agriculture as a fertilizer. This is in part to their high solubility in water.

There are 24 valence electrons available for the Lewis structure for NO3-.

It is helpful if you:

  • Try to draw the NO3- 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 Nitrate ion.
