define activity series of metal.arrange the metal gold copper iron and magnesium in order of their increase in reactivity
Answers
I didn't understand the question because there is no (;).
In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression[1] of a series of metals, arranged by their "reactivity" from highest to lowest.[2][3][4] It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores.
