The following table shows the activity series for some of the more common metals in order of deceasing reactivity, with the most reactive metal at the top of the list. It should not be surprising to you to find the alkali metals at the top of the list and the more unreactive metals at the bottom of the list.
Use this table to predict single replacement reactions.
This is a reference table and will be available to you in examinations. Do not attempt to memorize this table.
