This application covers 44 terms and diagrams dealing with advanced Bonding Theories and molecular geometry. The terms used in this app are based on the free chemistry e-book from OpenStax.org.  The 44 items are presented in 3 sets.  The first two screens cover the terminology and the last screen covers molecular shapes presented as ball-and-stick drawings. Items covered include sigma and pi bonding, hybrid orbitals, bonding and anti-bonding orbitals, and more. The user must select the term that matches a given  definition. Each word set has a Study Screen for the user to read and review the information. The score is reported as an accuracy of the number of correct answers out of the total answers selected.
