Don't forget Exam 2 is occurring next class period (11.11 and 11.12)!
It covers information from units 1-4. Unit 1 was about mole conversions, dimensional analysis, and significant figures. Unit 2 was all about atomic theory, atomic models, electrons in atoms, and the wave nature of light and matter. Unit 3 was about the periodic table and specific trends in properties observed for elements. Unit 4 was about ionic and metallic bonding, ionic and properties, and the names and formulas of ionic compounds. There is a review document below...I suggest you use it.
