metals

Metals are those elements in the left two-thirds of the periodic table (including the lanthanides and actinides but excluding hydrogen) that are typically shiny solids at room temperature and share the characteristic properties of high electrical and thermal conductivity, malleability, and ductility with high tensile strength.

Heating copper acetate to form a metal mirror
Simple formation of metal mirrors

I have always been fascinated by chemical reactions that form shiny, metallic mirrors.
2 silver colored penny and one copper one with text underneath: Plating Pennies with Tin
Plating Pennies with Tin
// Tuesday, February 2, 2021 • Tom Kuntzleman
One of my favorite chemistry demonstrations is the “Copper to Silver to Gold” experiment1 (VIDEO 1), in which a penny is first plated with zinc and then heated to form brass, an alloy of copper and zinc. The heat causes zinc to diffuse into the copper in the penny. The zinc plate imparts a beautiful silver color to the penny.

Chemical Tests on Coins
// Monday, September 16, 2019 • Tom Kuntzleman
I recently shared some simple experiments using magnets and coins that connect to the 2019 National Chemistry Week (NCW) theme, “Marvelous Metals!”1 Because coins are familiar items, made of metal, and so very easy to obtain, I think doing experiments with coins is a great idea for NCW 2019!
Simple Electroplating Demonstration
An Easy Copper Electroplating Demo for Your Redox Unit
// Sunday, November 20, 2016 • LowellThomson
My IB seniors are just wrapping up our unit on electrochemistry and redox. This has always been a challenging topic within the IB curriculum. Admittedly, electrochemistry has not ever been my strong suit either, so this year I aimed to strengthen the unit with two additional demonstrations.
Relative Reactivities of Metals
// Thursday, December 17, 2015 • Dan Meyers
Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.
