CHEM 111 Chapter 8 Objectives (Chang 10) Dr. Gnezda Be able to recognize and draw the following geometric shapes: trigonal planar tetrahedral trigonal bipyramidal octahedral Be able to do the following: 1. Identify the following regions of the periodic table: representative elements, noble gases, transition elements, lanthanides, actinides, metals, nonmetals, metalloids (see Figures 8.3 and 2.10). 2. Know the regions of the periodic table where the valence (outer shell) electrons are in s, p, d, or f orbitals (see Fig. 7.28). 3. Know that the elements in any given group have similar outer shell electron configurations. 4. Know that elements hydrogen, oxygen, nitrogen, and the halogens exist as diatomic molecules and the noble gases exist as monatomic species. Know that the stable form of phosphorous is P 4 . 5. Write electron configurations for cations and anions. 6. Recognize electron configurations that are isoelectronic. 7. Know that transition metal cations are made by removing electrons from the outermost

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
