Gould) (Questions from hapter 1 of the textbook) hydrogen helium 2 e lithium 3 Li beryllium 4 Be boron 5 B carbon nitrogen 7 N oxygen fluorine 9 F neon 10 Ne sodium 11 Na magnesium 12 Mg aluminium 13 Al silicon 14 Si phosphorus 15 P sulfur 16 S chlorine 17 l argon 18 Ar potassium 19 K calcium 20 a scandium 21 Sc titanium 22 Ti vanadium 23 V chromium 24 r manganese 25 Mn iron 26 Fe cobalt 27 o nickel 28 Ni copper 29 u zinc 30 Zn gallium 31 Ga germanium 32 Ge arsenic 33 As selenium 34 Se bromine 35 Br krypton 36 Kr rubidium 37 Rb strontium 38 Sr yttrium 39 Y zirconium 40 Zr niobium 41 Nb molybdenum 42 Mo technetium 43 Tc [98.91] ruthenium 44 Ru rhodium 45 Rh palladium 46 Pd silver 47 Ag cadmium 48 d indium 49 In tin 50 Sn antimony 51 Sb tellurium 52 Te iodine 53 I xenon 54 Xe cesium 55 s barium 56 Ba lutetium 71 Lu hafnium 72 f tantalum 73 Ta tungsten 74 W rhenium 75 Re osmium 76 s iridium 77 Ir platinum 78 Pt gold 79 Au mercury 80 g thallium 81 Tl lead 82 Pb bismuth 83 Bi polonium 84 Po [208.98] astatine 85 At [209.99] radon 86 Rn [222.08] 1. Explain how to determine how many electrons an element has using the Periodic Table. (30 seconds) 2. Explain the relationship between the elements in any of the vertical columns. Explain the relationship between the elements in any of the horizontal rows. (30 seconds) 3. A student in your class does understand the point of the periodic table. onvince this student of the utility of the Table, both historically to chemists, and also to the student. (60 seconds)

2 Now please look at the six pictures below, which give some different representations of chemicals. Look at the various structures, think about the relationship between the various representations, then answer the questions Explain why we need different ways to describe chemicals. Your explanation should include descriptions of each of the structures types shown in all of the panels. (60 seconds) 5. Explain the difference between the structures in panels 4 and 6 (30 seconds). 6. A student is lazy and wants to describe all structures as shown in panel 4. Explain to him why this is not a good idea. (45 seconds) 7. Explain the advantages and disadvantages of showing all chemical structures as illustrated in panel 2. (60 seconds)

3 Now I d like to hear your ideas about several topics. Be sure to say as much as you can in responding to each question. 8. Many students know the difference between ionic and covalent structures, but often do not know whether a particular structure will be ionic or covalent. What can you say to the students that will help them in this problem?. (60 seconds) 9. When you give your introductory lecture on atomic structure, several of the students start to look bored and distracted. What questions ideas can you think of to keep the students engaged in a lecture on this subject? (60 seconds)

10. The graph below presents the first ionization potential of several elements as a function of atomic number. Please explain the trends that you see. (60 seconds) 11.

4 10. The graph below presents the first ionization potential of several elements as a function of atomic number. Please explain the trends that you see. (60 seconds) 11. The element after neon in atomic number is sodium. Based on what you know about this plot, and also the periodic table, would you expect the ionization potential of sodium to be larger than that of neon, or smaller? Explain why. (45 seconds)

5 12. Now imagine that you are TA'ing an organic chemistry class. The following changes need to be made to the syllabus. Please announce these changes to your class. (90 seconds).
