Study Sheet for Chapter 7 - Covalent Bonding The student must be able to 1. Describe the differences between covalent and polar covalent bonding; know examples of each type. 2. Use electronegativity from the proceeding chapter to predict the type of bond which might be formed. Know the most electronegative elements and the least electronegative ones to be able to use in predicting bond types. 3. Describe what is meant by bond polarity and dipole moments. 4. Use the methods of writing electronic configuration of elements from the proceeding chapter to write the electronic configuration of cations and anions. 5. Describe the ionic size of ions in terms of the periodic table. 6. Draw Lewis electron dot structures to show bonding and lone pairs of electrons in simple covalent compounds and binary ionic compounds. Recognize the "octet" rule and

Be able to correctly draw the resonant structures of compounds and ions that exhibit this phenomenon. 8. Use the valence shell electron pair repulsion model (VSEPR) to predict the geometry of simple compounds. 9. Use hybridization of atomic orbitals to predict the bond angles and geometry of simple molecules.

    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.
