Question

What is reactivity series???​

Answer 1

The activity series (also known as reactivity series) of metals is a series in which metals arranged in the decreasing order of reactivity. Thus the most reactive metal is placed at the top of the series while the least reactive metal is placed at the bottom of the series.

Answer 2

Answer:

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.

Going from the bottom to the top of the table the metals:

   increase in reactivity;

   lose electrons (oxidize) more readily to form positive ions;

   corrode or tarnish more readily;

   require more energy (and different methods) to be isolated from their compounds;

   become stronger reducing agents (electron donors).
