Chap 2: Atomic Structure
Goals: 2.1 Historical Development
The periodic table
- Briefly describe the organization of Mendeleev's table (ordered by, grouped by)
- Briefly describe what drove acceptance of Mendeleev's table
2.2 The structure of the atom
- Briefly describe the milestones in the description of the atom
- Describe how a classical particle in a box and a quantum mechanical particle in a box differ.
- Describe what the n, l, ml, and ms quantum numbers tell us about an electron
- Identify allowed and impossible combinations of quantum numbers
- Briefly describe what the radial and angular functions tell us about the probability of finding an electron at a given point
- Briefly describe the two types of nodal surfaces
- Be able to determine the number of angular and radial nodal surfaces in a given orbital
- Write electron configurations and draw energy level diagrams for a given atom
- Use Slater's method for calculating Zeff and describe the limitations of Slater's method
- Explain ground state electron configurations using principles such as shielding, effective nuclear charge, coulomb repulsion, etc.
Goals: 2.3 Periodic Trends
Ionization Energy, Electron Affinity, and Size
- Know the trends
- Explain the trends
- Rationalize the breaks in the trends
