1. Periodicity Review

2. the idea of periodicity the idea of periodicity these trends across a period and down a family: these trends across a period and down a family: reactivityreactivity acid-base natureacid-base nature Combining ratio for elements in the same familyCombining ratio for elements in the same family atomic radiusatomic radius First ionization potentialFirst ionization potential melting pointmelting point boiling pointboiling point Atomic number and atomic massAtomic number and atomic mass

3. Labs to review include Metals/NonmetalsMetals/Nonmetals Properties of each, property requirements for metalloids, location of each type of element on the periodic table Properties of each, property requirements for metalloids, location of each type of element on the periodic table Investigating Periodic and Family TrendsInvestigating Periodic and Family Trends Chemical reactivity Chemical reactivity Acid and base nature Acid and base nature Elements combining ratio Elements combining ratio Family Characteristics Graphing ActivityFamily Characteristics Graphing Activity Atomic radius Atomic radius First ionization energy First ionization energy Melting and boiling point Melting and boiling point **If you wrote a good lab report with full sentence answers to the questions and a good conclusion, then reviewing your lab report will be very helpful.
