- 8.1: General Trends in Main Group Chemistry
- 8.1.1: The Periodic Table is an Organizing Concept in Main Group Chemistry
- 8.1.1.1: The metal-nonmetal-metalloid distinction and the metal-nonmetal "line" are useful for thinking about trends in elements' physical properties
- 8.1.1.2: There are qualitative differences in the chemistry of the elements in the first two rows and those in the rest of the periodic table
- 8.1.2: Electronegativity increases and radius decreases towards the upper left of the periodic table, with electron withdrawing substituents, and with oxidation state
- 8.1.3: Ionization energy roughly increases towards the upper left of the periodic table but is also influenced by orbital energy and pairing energy effects
- 8.1.4: As may be seen from considering element's redox diagrams, main group elements (aside from the noble gases) generally are more oxidizing towards the upper left of the periodic table and more reducing towards the lower right of the periodic table
- 8.1.4.1: Latimer Diagrams summarize elements' redox properties on a single line
- 8.1.4.2: Frost Diagrams show how stable element's redox states are relative to the free element
- 8.1.4.3: Pourbaix Diagrams are Redox Phase Diagrams that Summarize the most stable form of an element at a given pH and solution potential
