This is an Excel spreadsheet that contains the radial factors of the H-atom wavefunctions for the 1s, 2s, 2p, 3s, 3p, 3d, and 4s orbitals as a function of multiples of the Bohr radius.  Plots are also included of the radial factors (R) vs. r and the radial probability distribution (4πr²R²) vs. r.  These can be used during lecture to illustrate to students how these plots change for each type of orbital, or for different principal quantum numbers, or for changing effective nuclear charge.

This is an assignment designed to help students begin to reflect on professional ethics of scientific practice.  I have used this in a freshman and a senior seminar after 2-3 days of discussion of what professional ethics is and how one goes about choosing a course of action in an ethical dilemma.  I use:

Students practice assignment of symmetry elements and point groups, practice developing a character table, and learn about the link between orbitals and irreducible representations.

This is a worksheet on Lewis structures and formal charges. The learning goal is for students to be able to use formal charges to defend the relative stabilities of resonance structures of molecules.

It’s very surprising how little students remember from general chemistry.  This assignment helps students make connections between the macroscopic properties of solutions and what happens at the molecular level.  This activity serves as a bridge between sections on acid-base chemistry and coordination chemistry.

Students are solicited for their models of the behavior of different chemical compounds in water in class and asked to put these models on the board.  We then look at the properties of these solutions (color, acid-base) and refine these models in class.
