Thoughts: Questions:

Ask if there is any evidence that the charge on the metal ions effects the reactivity of the metal ions.

Consider the table of chemical reactions (these type of chemical equations are called half-reactions) you constructed in the BCE and consider the following definitions;

oxidation is the process of losing electrons;

reduction is the process of gaining electrons;

Based on these definitions what is the process illustrated in the table from the BCE?

What kind of half - reactions are written in the table?

What would you need to do to the chemical equations to illustrate the other process.

Groups of reduction half-reactions written in the relative order they are written in this table is called an Activity Series.

Consider the second most active metal in the table. What metal ions react with that metal, and what metal ions do not react with that metal?

Consider the position of the reactive and the nonreactive metal ions to make a rule based on the position of the metal and metal ions in the activity series table that allows one to predict what metal ions will react with what metals.

The ACA will use Tom's metal/metal ions simulation to do one of the Activities and come up with the activity series that is appropriate.
