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!
