Unit One: Atomic Structure and Properties (Electron Structure, Periodicity)

Goals of Unit 1 include:

• Conceptual understanding of both the Bohr model of the atom and the Quantum Mechanical model of the atom, including quantum numbers

• Writing electron configurations, both excited and ground state, for elements using nothing but a periodic table

• Interpretation of mass spectroscopy (MS) data.

• Interpretation of photoelectric spectroscopy (PES) data.

• Understanding how electron and atomic structure relates to the concepts of atomic size, ionic size, and ionization energy.

• Predicting trends in reactivity based on position in the periodic table.

Solution Stoichiometry (not Unit 1, but we're doing it anyway) Lab Resources

• Prelab Video Part 1 - What is a Job Plot?

• Prelab Video Part 2 - OK, so what are we actually doing in the lab?

  • NOTE: in the video, I erroneously refer to the solutions being 0.10M. That is not the case; our solutions will be 1.0M.

• How to make a Job Plot in Google Sheets

• Solution Stoichiometry Lab Handout

• Prelab slides (accompany the videos) for Solution Stoichiometry Lab

Unit 1 Lecture Videos

1. Review of Bohr model of the atom (not me but a colleague of mine)

2. The Organizational System of the Quantum Mechanical Model (me, but this is my Regents Video)

3. Paramagnetism and Diamagnetism, and the penetration effect

4. Exceptions to Electron Configuration

5. Coulomb's Law (not me)

6. Periodicity Review (Bozeman Science)

7. Relative sizes of orbitals, Successive Ionization Energies, Electron Affinity

8. Photoelectron Spectroscopy (Bozeman Science)

Slides and Handouts for Unit 1:

• Unit 1 Note Packet (corresponds with lecture videos)

• Unit 1 Practice Packet
