9.1d Activity series

Activity series show oxidizing power (so you know which way the electrons are moving)

Example:

If a piece of Zinc and a piece of Copper are put together, the piece of Zinc will oxidize = lose electron to the piece of Copper. Why? Think back to Electron affinity Periodicity unit

More on this when we look at voltaic vs. electrolytic cells
