Name: _______________________________________ Period: __________ Score: __________ Problem Set 13: Wave-mechanical Model Major Concepts Students learn the wave-mechanical model Identify inadequacies on the Rutherford atomic model Identify the new assumption in the Bohr model of the atom Describe the energies and positions of electrons according to the quantum mechanical model Describe how the shapes of orbitals at different sublevels vary Describe the relationship between the wavelength and frequency of light Explain how the frequencies of light are related to changes in electron energies Distinguish between quantum mechanics and classical mechanics Identify the cause of the atomic emission spectrum Reading Chapter 11.2, 11.3, 11.5, & 11.6 Using one paragraph per section, summarize the two sections you just read. Reading Guide Complete Reading Guide 13 Lab Complete Lab 13 Lecture Notes Print and read Lecture 13 from TheChemBook; Combine your notes from class with the notes on TheChemBook. Use the Cornell Notes Strategy to review your notes each night (5 min.). Vocabulary Define each vocabulary word. Electromagnetic radiation (p. 324) Frequency (p. 324) Photons (p. 325) Quantized (p. 329) Wavelength (p. 324) Wave mechanical model (p. 331) Questions and Problems 1. What is meant by electromagnetic radiation? Give examples. 2. What is a packet of electromagnetic energy called? 3. What is the relationship between wavelength of light and the energy of photons? 4. What is wrong with the Bohr model of the atom? 5. How does the wave mechanical model of the atom differ from Bohr’s model? 6. What does it mean to say that an atom is in an “excited state”? 7. Discuss briefly the difference between an orbit (as described by Bohr for hydrogen) and an orbital (as described by the wave mechanical model).
