A step-by-step explanation of how to draw the HNO2 Lewis Structure (Nitrous Acid). • When we have an H (or H2) in front of a polyatomic molecule (like CO3, SO4, NO2, etc.) we know that it's an acid. This means that the Hydrogen atoms will be attached to the outside of the oxygen molecules. Not knowing this information makes it very difficult to draw the Lewis structure for HNO2. • For the HNO3 structure use the periodic table to find the total number of valence electrons for the HNO3 molecule. Once we know how many valence electrons there are in HNO3 we can distribute them around the central atom with the goal of filling the outer shells of each atom. • In the Lewis structure of HNO3 structure there are a total of 18 valence electrons. HNO3 is also called Nitric acid. • ---- Steps to Write Lewis Structure for compounds like HNO3 ---- • 1. Find the total valence electrons for the HNO3 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 Resources ---- • • Lewis Structures Made Simple: • How to Draw Lewis Structures: Five Ea... • • More practice: • Lewis Dot Structure Practice Problems... • • Counting Valence Electrons: • Finding the Number of Valence Electro... • • Calculating Formal Charge: • Formal Charges: Calculating Formal Ch... • • Exceptions to the Octet Rule: • Exceptions to the Octet Rule • 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 Nitric acid. 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). • Chemistry help at https://www.Breslyn.org
