Section 3 Activity Series of the
Elements
• The ability of an element to react is referred to as the
element’s activity.
• The more readily an element reacts with other substances, the
greater its activity is.
• An activity series is a list of elements organized
according to the ease with which the elements
undergo certain chemical reactions.
• For
metals,togreater

means a greater ease of loss of
electrons,
form positive
• For nonmetals, greater activity means a greater ease of gain
of electrons, to form negative ions.

Section 3 Activity Series of the
Elements
• The order in which the elements are listed is usually
determined by single-displacement reactions.
• The
most-active element is placed at the top in the
series.
• It can replace each of the elements below it from a
compound in a single-displacement reaction.
• certain

will occur.
• Activity series are based on experiment.
