Question

what is meant by reactivity series of metal? arrange different metals in the decreasing order of their reactivity​

Answer 1

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.

Given Question:-

What is meant by reactivity series of metal? arrange different metals in the decreasing order of their rreactivity.

Required Answer:-

Reactivity series of metals is a chart listing the most reactive metal at the top and the less reactive metal at the last.

It is also known as activity series.

The more reactive a metal is, the more vigorously it reacts with other substances.

The more easily it loses electrons to form positive ions (cations)

The reactivity series of metals is as follows:-

$\setlength{\unitlength}{0.8 cm}\begin{picture}(20,15)\thicklines\put(5,9.5){\large {\boxed{ \sf{Reactivity \:  series}}}}\put(0.8,8){\large\sf K \qquad\qquad\qquad Potassium\qquad\qquad\qquad \: maximum}\put(0.8,7.2){\large\sf Na \qquad\qquad\qquad Sodium\qquad\qquad\qquad\quad \: reactivity}\put(0.8,6.2){\large\sf Ca\qquad\qquad\qquad \: Calcium}\put(0.8,5.2){\large\sf Mg\qquad\qquad\quad \: Magnesium}\put(0.8,4.2){\large\sf Al\qquad\qquad\qquad \: Aluminium\qquad\qquad\qquad \: decreasing}\put(0.8,3.2){\large\sf Zn\qquad\qquad\quad\qquad \: Zinc\qquad\qquad\qquad\qquad \:reactivity}\put(0.8,2.2){\large\sf Fe\qquad\qquad\quad\qquad Ferrous}\put(0.8,1.2){\large\sf Pb\qquad\qquad\qquad \: \:\: Lead}\put(0.8,0.2){\large\sf H\qquad\qquad\qquad \:  \:Hydrogen}\put(0.8, - 0.6){\large\sf Cu\qquad\qquad\qquad \: Copper}\put(0.8, - 1.5){\large\sf Hg\qquad\qquad\qquad \: Mercury}\put(0.8, - 2.5){\large\sf Ag\qquad\qquad\qquad \: \:Silver}\put(0.8, - 3.5){\large\sf Au\qquad\qquad\qquad \: \:  Gold\qquad\qquad\qquad\quad \:  \: minimum reactivity}\put(9.3,8.2){\vector(0, - 2){12}}\end{picture}$
