Activity Series
The ability of an element to react is
called the element’s activity.
An activity series is a list of elements
organized according to the ease with
which the elements undergo certain
chemical reactions.
For metals, greater activity means a
greater ease of loss of electrons, to
form positive ions.
For nonmetals, greater activity means
a greater ease of gain of electrons, to
form negative ions.
Activity Series
The order in which the elements are listed
in an activity series is usually determined
by single-replacement reactions.
The most active element, placed at the top
in the series, can replace each of the
elements below it from a compound in a
single-replacement reaction.
An element farther down can replace any
element below it but not any above it.
Activity series are used to help predict
whether certain chemical reactions will
occur.

Question
How is the activity series useful in
predicting chemical behavior?
It helps predict whether a
chemical reaction will occur and
what the product(s) of the
reaction will be.
