  • 3.1: CHEMICAL BONDS, LEWIS SYMBOLS AND THE OCTET RULE

    Conceptual Problems

    1. The Lewis electron system is a simplified approach for understanding bonding in covalent and ionic compounds. Why do chemists still find it useful?
    2. Is a Lewis dot symbol an exact representation of the valence electrons in an atom or ion? Explain your answer.
    3. How can the Lewis electron dot system help to predict the stoichiometry of a compound and its chemical and physical properties?
    4. How is a Lewis dot symbol consistent with the quantum mechanical model of the atom? How is it different?
