| Video Discription | How to find the number of valance electrons for Hydrogen Cyanide (HCN). Finding the number of valence electrons for HCN is the first step in writing its Lewis Structure: For the HCN structure use the periodic table to find the total number of valence electrons for the HCN molecule. Once we know how many valence electrons there are in HCN we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of HCN structure there are a total of 10 valence electrons. HCN is also called Hydrogen Cyanide. ----- Steps to Write Lewis Structure for compounds like HCN ----- 1. Find the total valence electrons for the HCN 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. --- HCN Videos --- HCN Lewis Structure: https://youtu.be/Ap93tYTN8C4 HCN: Polar or Non-Polar: https://youtu.be/yseKsL4uAWM HCN Molecular Geometry: https://youtu.be/hKfnhXI55Fw ----- Lewis Resources ----- • Lewis Structures Made Simple: https://youtu.be/1ZlnzyHahvo • More practice: https://youtu.be/DQclmBeIKTc • Counting Valence Electrons: https://youtu.be/VBp7mKdcrDk • Calculating Formal Charge: https://youtu.be/vOFAPlq4y_k • Exceptions to the Octet Rule: https://youtu.be/Dkj-SMBLQzM 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 Hydrogen Cyanide. 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).
