activity series is prepared by comparing single displacement reactions between metals. based on observations, the metals can be ranked by their ability to react. however reactivity can be explained by ease with which atoms of metals lose electrons. using information from activity series identify the locations in the periodic table of the most reactive metals. using your knowledge of electron configurations and periodic trends, infer possible explanations for the metals reactivity and position in the periodic table.
