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 N2 (Dinitogen or Nitrogen Gas)

Nitrogen (N2) is a commonly tested Lewis structure due to its importance on Earth (about 78% of the Earth's atomsphere is N2). It also is a good example of a molecule with a triple bond.

There are 10 valence electrons available for the Lewis structure for N2.

Video: Drawing the Lewis Structure for N2

It is helpful if you:

  • Try to draw the N2 Lewis structure before watching the video.
  • Watch the video and see if you missed any steps or information.
  • Try structures similar to N2 (like C2H2) for more practice.
