How to Draw the Lewis Dot Structure for NO2: Nitrogen dioxide

A step-by-step explanation of how to draw the NO2 Lewis Dot Structure (Nitrogen dioxide).

For the NO2 structure use the periodic table to find the total number of valence electrons for the NO2 molecule. Once we know how many valence electrons there are in NO2 we can distribute them around the central atom with the goal of filling the outer shells of each atom.

In the Lewis structure of NO2 structure there are a total of 17 valence electrons. NO2 is also called Nitrogen dioxide.

---- Steps to Write Lewis Structure for compounds like NO2 ----
1. Find the total valence electrons for the NO2 molecule.
2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.
3. Put two electrons between atoms to form a chemical bond.
4. Complete octets on outside atoms.
5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures, also called Electron Dot Structures, are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Nitrogen dioxide. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
