Nobel Prizes

Submitted by Maggie Geselbracht / Reed College on Sun, 01/27/2008 - 18:08
Description

This is a list of Nobel Prizes that in my opinion were either in Inorganic Chemistry or in an area that has impacted Inorganic Chemistry.  I pass this out to students on the first day of class when we are talking very generally about what inorganic chemistry is all about.  This could be extended into a longer discussion at this point or at a later point on one or more of the prizes.  For example, later in the semester I have them read the Nobel Prize address of Alfred Werner.  This helps to inform their lab work and introduces coordination chemistry, which we have not yet discussed in lectu

H atom radial factors

Submitted by Maggie Geselbracht / Reed College on Sun, 01/27/2008 - 17:46
Description

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.

Two Communications on Bioinorganic and Coordination Chemistry

Submitted by Hilary Eppley / DePauw University on Fri, 01/04/2008 - 20:39
Description
This assignment would make a good choice for a first attempt at actually having a discussion on primary literature articles since these are two short communications. They also touch on two important applications of coordination chemistry so might be appropriate early in a course, namely modeling biological systems and non-linear optical applications.

Personal Radiation Dose

Submitted by Lori Watson / Earlham College on Fri, 01/04/2008 - 18:43
Description
I mostly use this exercise as a "see, most of your radiation does is NOT from nuclear plants."  I have used this in both General Chemistry and Inorganic Chemistry when doing a nuclear chemistry or energy production unit.

Bercaw vs Bergman

Submitted by Adam Johnson / Harvey Mudd College on Fri, 01/04/2008 - 13:26
Description

Relative metal-hydrogen, -oxygen, -nitrogen, and -carbon bond strengths for organoruthenium and organoplatinum compounds; equilibrium studies of Cp*(PMe3)2RuX and (DPPE)MePtX systems
Henry E. Bryndza, Lawrence K. Fong, Rocco A. Paciello, Wilson Tam, John E. Bercaw
J. Am. Chem. Soc.; 1987 ; 109(5); 1444-1456.

Point groups and character tables

Submitted by Joanne Stewart / Hope College on Sun, 11/18/2007 - 14:27
Description

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

Lewis structures and formal charges

Submitted by Joanne Stewart / Hope College on Sun, 11/18/2007 - 14:17
Description

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.

Descriptive Chemical Jeopardy

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Sun, 11/18/2007 - 13:55
Description

Students assigned a portion of the periodic table.  Generally, a student is given a column of the main group, but this can easily be varied, depending on the size of the class.

From molecules to solids: Lewis structures

Submitted by Barbara Reisner / James Madison University on Sun, 11/18/2007 - 13:19
Description

I have students construct Lewis structures on the board starting at the noble gases and working backwards to the group 14 elements.  We talk about both second period then heavier elements.  As we move across the period we transition from molecular solids to extended solids.  

This is a nice transition from molecular chemistry to extended compounds.  I use this as a bridge into the solid state portion of the course because it allows me to review Lewis structures, trends in bond energies, and provide some descriptive chemistry information. 

What happens when chemical compounds are added to water?

Submitted by Barbara Reisner / James Madison University on Sat, 11/17/2007 - 18:38
Description

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.
