Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu 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, greater activity means a greater ease of loss of electrons, to form positive ions. Section 3 Activity Series of the Elements Chapter 8 For nonmetals, greater activity means a greater ease of gain of electrons, to form negative ions.

Copyright © by Holt, Rinehart and Winston. All rights reserved. ResourcesChapter menu 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. Section 3 Activity Series of the Elements Chapter 8 It can replace each of the elements below it from a compound in a single-displacement reaction. Activity series are used to help predict whether certain chemical reactions will occur. Activity series are based on experiment.
