BSC2010 Exam #1 Study Guide Covering Chapters 2-5To remind you, the exam itself is 50 questions consisting of T/F and multiple-choice questions worth 1.5 points/each for a total of 75 points. I ask an equalnumber of questions from each chapter. This review is meant to focus your study effort but is not meant to be all inclusive; there can be things on the exam that are not covered in this guide. However, if you use this guide wisely and study efficiently, an ‘A’ or ‘B’ is readily within your reach. Materialfor the exams can come from your text book, my Power Point presentations, or Mastering quiz and homework assignments (more so the quizzes than the homeworks I would say). Also remember that for this first exam, you are not tested over Chapter 1 or the syllabus. I will of course provide Scantrons for you, but you will need a valid PHOTO ID and #2 pencil. You will not need a calculator or a periodic chart either. You have 75 minutes to complete the exam.In every chapter, words which appear in boldare worth knowing, and I recommend making flash cards for these. I also recommend focusing on the Level I and Level II questions at the end of each chapter, as exams are not just about regurgitating facts but also include some synthesis and analysis problems. Study groups do help, in my opinion, and can be formed readily using the Group Discussion Board on Canvas. Chapter 2: In addition to knowing the bolded terms in this chapter, make certain you understand the concepts behind each. For example, you know I’m sure that a cation is positively charged, but what would make a particular atom have this excess of a positive charge? An atomcan have an excess positive charge do to its valence electrons and bonding characteristics Likewise, you know that isotopes of an element differ in the number of neutrons each has, but how does this affect other aspects of the atom, if at all? The different isotopes can have different atomic mass, and radioactive isotopes decay spontaneously giving off particles and energy. Applications for the radioactive isotopes can be for dating fossils, tracing atoms through metabolic processes and diagnosing medical disorders.What information can things like the atomic mass, atomic number, and atomic mass number tell you about an atom? What determines each? AtomicMass if the addition of the protons and neutrons in the atom, Atomic Number is the number of protons an atoms have. The Atomic number can tell you it electron negativity and valence electrons or electron shells. What is the nature of the various subatomic particles which comprise an atom? A protons are positively charged and electron are negatively charged and neutron are neutral.
