Turning Plastic Into Gold: An Analogy To Demonstrate the Rutherford Gold Foil Experiment Robert B. Gregory
Describes an in-class demonstration designed to be an analogy to the RutherfordGeigerMarsden gold foil experiment that requires only a laser pointer, two picture frames, and a sheet of plastic.

Color My Nanoworld Adam D. McFarland, Christy L. Haynes, Chad A. Mirkin, Richard P. Van Duyne, and Hilary A. Godwin
This activity begins with the synthesis of 13 nm-diameter gold nanoparticles by reduction of a gold salt. The students use the resulting nanoparticle solution to explore the size-dependent optical properties of gold nanoparticles.

A Chemical-Medical Mystery: Gold Jewelry and Black Marks on Skin Barbara B. Kebbekus
Gold jewelry at times makes a black mark or smudge on skin. This may be caused by abrasive powders on the skin (e.g. zinc oxide) but the phenomenon may also be caused by other skin conditions, possibly the presence of chloride ion, acidity, or sulfur-containing amino acids.

Why Gold and Copper Are Colored but Silver Is Not Ariel H. Guerrero, Héctor J. Fasoli, and José Luis Costa
Interpretation of the yellow color of gold based on an adequate external electronic configuration (s1d10/s2d9) and s and d sublevels close enough to allow transition between them to proceed significantly.

The Nernst Equation: Determination of Equilibrium Constants for Complex Ions of Silver Martin L. Thompson and Laura J. Kateley
The experiment requires a voltmeter capable of recording millivolts (or a good pH meter) and inexpensive chemicals. It allows students to check the validity of the Nernst equation and compare their experimental Kform values to reported ones.

The extraction of gold and its simulation with copper Bradley, J. D.; Brand, M.; Louli, J. A. M.
The simulation of the extraction of gold by the use of its analog, copper, makes it possible to capitalize on the glamor of gold without sacrificing any chemical principles.
