CHEM 111 Chapter 7 Objectives (Chang 10) Dr. Gnezda Be able to do the following: 1. Know the symbols for wavelength ( λ ), frequency ( ν ), speed of light (c), and energy (E). 2. Know that light (electromagnetic radiation) travels at 3.00 x 10 8 m/s in a vacuum. 3. Relate wavelength to frequency using the equation c = λ•ν. (See Example 7.1). 4. Know the major regions of the electromagnetic spectrum and their relative frequencies, wavelengths and energies. 5. Using the equation E = h ν , calculate the energy of a photon of light given its frequency or wavelength (see Example 7.2). 6. Describe the Bohr model of the hydrogen atom. Describe what happens to the electron when it absorbs energy and when it releases energy (emits light). 7. Define and explain the following terms: ground state, excited state, Pauli Exclusion Principle, Hund's Rule, Aufbau Principle. 8. Describe the three quantum numbers ( n , l , m l ) that define a given orbital of an atom. 9. List the allowed values for n , l ,

Unformatted text preview: m l , and m s . Examine sets of quantum numbers and determine if they are allowed or not allowed. 10. Assign orbital names to allowed sets of quantum numbers. 11. Sketch the shapes of the following orbitals: s, p x , p y , p z , d xy , d xz , d yz , d x2-y2 , d z2 . (see Figures 7.19, 7.20 and 7.21) 12. Using the Aufbau method, write ground state electron configurations for atoms. Know that Cr and Cu are important exceptions to the Aufbau method. 13. Know the regions of the periodic table where the valence electrons are in s, p, d, or f orbitals (see Fig. 7.28). 14. Determine whether an element in its ground state is diamagnetic or paramagnetic. Assigned problems to work (These problems will not be collected): 7.2, 7.3, 7.8, 7.16, 7.18, 7.20, 7.47, 7.48, 7.50, 7.52, 7.53, 7.54, 7.56, 7.58, 7.60, 7.62, 7.64, 7.66, 7.68, 7.70, 7.72, 7.74, 7.76, 7.77, 7.79, 7.81, 7.82, 7.84, 7.86, 7.88, 7.90, 7.92, 7.96, 7.110, 7.113, 7.114, 7.115, 7.124, 7.132...

    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.
