Review For Final This is by no means a comprehensive review. I have made this review sheet by looking at previous midterms and quizzes and noting the common mistakes made by students. In order to do your best on the final, you should go through your lecture notes, HW, and exams/quizzes carefully. I. Exam I/Quiz 1: A. Electron Configurations: a. When we ionize a transition metal with configuration ns 2 (n-1)d, the first two electrons ALWAYS come from the ns orbital Example: The electron configuration of Mn 2+ is [Ar] 3d 5 rather than [Ar] 4s 2 3d 3 b. A substance is paramagnetic if it has ANY unpaired electrons. A substance is diamagnetic if it has ALL paired electrons. It is rare for a substance to be diamagnetic. Example: Mn 2+ is paramagnetic because it has 5 unpaired electrons c. Elements which are in the same group of the periodic table have the “same chemical behavior” because they have the same valence configuration B. Basic Rules for writing reactions: a. Remember which elements on the periodic table are solids at room temperature and which are liquids b. Commit to memory or write down the solubility rules for inorganic compounds (page F65 of your text). When two reactants form an insoluble product, the phase of that product will be solid (s).
