Lewis Structures

Subject: Chemistry

Book: General Chemistry

Lewis structures are diagrams showing how valence electrons are distributed among atoms in a molecule or ion. Dots represent electrons, while lines represent shared pairs (bonds). Drawing a correct Lewis structure helps determine bond order, formal charges, and molecular geometry. It is the foundation for predicting reactivity and understanding resonance, which occurs when multiple valid Lewis structures exist. Mastery of Lewis structures is essential for deeper study of organic and inorganic reactions.
