Unformatted text preview: Chapter 6: Electronic Structure of Atoms CH110 FA11 SAS 1 Prepare for Recitation September 8 th ALEKS Objective 2 due September 6 th ANGEL Quiz 2, September 8 th Lecture 5: August 31 st Lecture 6: September 2 nd Labor Day Holiday: September 5 th You are advised to re-read Ch. 6.1-6.6 in addition to the work shown below in order to help you see the big picture for this section of the course. Read: Ch. 6.7 6.9 Additional Preparation*: BLB 6 : 33,39,54; Packet 6 : 6-9 * ALEKS work is necessary but not sufficient for exam level preparation! Do not neglect the packet! Chapter 6: Electronic Structure of Atoms CH110 FA11 SAS 2 By the end of Lecture 6 you should know: wavelength and frequency of light, dual nature of light, electronic transitions and line spectra Bohr model Matter acts as waves Heisenberg Uncertainty Principle Electronic transitions of orbitals Quantum numbers (n, , m , m s ) Orbitals: their shapes and energies Orbitals and atoms with many electrons Spin quantum number (m s ): Pauli Exclusion Principle and Hunds Rule Electron Configurations using the periodic table What is the structure of an atom? What are the properties of atoms? Remember: structure affects function! Where are the electrons located? What is the energy of an electron? KEY QUESTIONS: THE BIG PICTURE Concept Check CH110 FA11 SAS 3 Understanding electromagnetic energy led to quantum theory (it explains what we observe) which led to atomic structure and predicts electron configurations and explains periodic trends of the elements So electrons are found in Orbitals CH110 FA11 SAS 4 1. Principal quantum number: _________ n= 2. Azimuthal quantum number : 2....
