Question

Define activity series, and write the decreasing order of metals​

Answer 1

Explanation:

The series which arranges metals in the decreasing order of reactivity is known as the reactivity series. Thus, the least reactive metal is placed at the bottom while the most reactive metal is placed at the top of the series.

For e.g :- Potassium

                Sodium

                Lithium

                Calcium

                Magnesium

                Zinc 

                Iron

                Copper

Answer 2

$\huge\underline\mathtt{Answer}$

Reactivity series is a series of metals which are arranged from highest to lowest according to their reactivity. ... The decreasing order of reactivity of Zn, Mg, Al, Cu, Fe is Mg > Al > Zn > Fe > Cu. Reactivity series is K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Hg > Ag > Au.
