Let Us Give Lewis Acid–Base Theory the Priority It Deserves  Alan A. Shaffer
The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

Lewis structures are drawn using a simplified novel method with the following features: 1) the atoms used are brought in carrying all their valence electrons; 2) bonds are created by pairing up valence electrons between the central atoms and peripheric atoms; 3) anions are formed by addition of electrons to single electrons on appropriate atoms, while cations are formed by removal of single electrons.
