How to find the number of valance electrons for Ammonia (NH3). Finding the number of valence electrons for NH3 is the first step in writing its Lewis Structure: • In the Lewis structure of NH3 structure there are a total of 8 valence electrons. NH3 is also called Ammonia. • ---- Steps to Write Lewis Structure for compounds like NH3 ---- • 1. Find the total valence electrons for the NH3 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 Ammonia. 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
