Chap 6: Electronic Structure and the Periodic Table
Goals: Chapter 6.1 Light, Photons Energies, and Atomic Spectra
- Calculate wavelengths from frequencies and vice versa for light
- Determine the energy of a photon
- Know which end of the electromagnetic spectrum is the low energy end and which is the high energy end
- Describe how line spectra support the idea that the energy of an electron is confined to specific levels for a given atom
Chapter 6.2 The Hydrogen Atom
- Describe how Bohr constructed his model of the H atom
- Understand that quantum mechanics works by treating the electron as a wave
- Describe the trade off between kinetic energy of an electron as it gets closer to the nucleus and the potential energy of an electron as it gets closer to a nucleus
Goals: Chapter 6.3 Quantum Numbers
- Be able to recognize allowed and allowed combinations of quantum numbers
- Compare Bohr's idea about quantum numbers to the quantum numbers produced by quantum mechanics
- Be able to determine orbital type from a set of quantum numbers
Goals: Chapter 6.4 Atomic Orbitals; Shapes and Sizes
- Recognize orbital type (s, p, d, f) from graphic representations
- Sketch s, p, and d orbitals
- Compare orbitals that have identical l values but different n values (Compare orbitals from different rows of the periodic table)
Goals: Chapter 6.5 Electron Configurations in Atoms
- Determine ground state electron configurations for neutral atoms and ions
- Recognize excited state electron configurations
Goals: Chapter 6.6 Orbital Diagrams of Atoms
- Draw energy level diagrams for atoms and ions
- Explain the distribution of electrons in energy level diagrams (pair vs unpaired electrons in degenerate orbitals)
- Recognize energy level diagrams that represent excited states
Goals: Chapter 6.8 Periodic Trends in the Properties of Atoms
- Use trends to compare the properties (ionization energy, size, and electronegativity) of atoms
- Explain the trends using electron configurations, nuclear charge, shielding, and distance
Goals: Chapter 6.7 Electron Arrangements in Monatomic Ions
- Determine the likely charges for main group ions
- Explain the likely charges of main group ions using electron configurations
- Describe the difference between valence and core electrons
