In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. 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.

Hello There!

The reactivity series of metals in Chemistry is the order of reactivity. That is, it is a tabular form of metals, which tells us which metal is more reactive and which metal is less, for a comparative study of reactivity between two or more metals.

Here’s the reactivity series:

K
Na
Ca
Mg
Al
Zn
Fe
Ni
Sn
Pb
H
Cu
Hg
Ag
Au
Pt

The metals above Hydrogen can easily displace hydrogen from dilute acids, but metals below, can’t. Gold is a noble metal.

The trick which my friends used is:
Kangaroo (K)
Never (Na)
Can (Ca)
Marry (Mg)
A (Al)
Zebra (Zn)
For (Fe)
Non (Ni)
Soluble (Sn)
Pokemon (Pb)
H
and then Copper – hydrogen – and metals with increasing cost: silver, gold, platinum.

Seems silly, but you can use this.
Thanks!

The easiest way to remember reactivity series of metals is -
Kangaroo (K)
Never (Na)
Can (Ca)
Marry (Mg)
All (Al)
Zebras (Zn)
For (Fe)
Some (Sn)
People (Pb)
Have (H)
Committed (Cu)
Him (Hg)
