INORGANIC Nomenclature Nomenclature - Humor “Ferrous Wheel” Fe = iron (Latin = ferrum) Fe 2+ = lower oxidation state = ferr ous Fe 3+ = higher oxidation state = ferr ic BaNa 2 “ BaNaNa Chapter 11 – Transmembrane Transport of Ions and Small Molecules Chapter 11 – Transmembrane Transport of Ions and Small Molecules 11.1 Overview of Transmembrane Transport 11.2 Facilitated Transport of Glucose and Water Early in the 19. th. century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first.. 3-. 2. Questions for Consideration. How do ionic compounds differ from molecular compounds?. What kinds of ions are in ionic compounds?. What do formulas for ionic compounds represent?. How are ionic compounds named?. Polyatomic Ions .
