H2O Lewis Structure: Lewis Dot Structure for H2O

A step-by-step explanation of how to draw the H2O Lewis Dot Structure (Water). For the H2O structure use the periodic table to find the total number of valence electrons for the H2O molecule. Once we know how many valence electrons there are in H2O we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of H2O structure there are a total of 8 valence electrons. H2O is also called Water. A frequent error is to start with HO2 (really, this happens quiet often), Be sure that you have two hydrogen and one oxygen atoms. ---- Steps to Write Lewis Structure for compounds like H2O ---- 1. Find the total valence electrons for the H2O 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 Water. 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).
