Question

define activity series of metals. arrange metals gold copper iron and magnesium in increasing order of reactivity series..

Answer 1

The series In which metals are arranged in the increasing of decreasing order of reactivity. This reactivity is decided by conducting various laboratory experiments.

The increasing order of reactivity would be.
Gold ( Au )
Copper ( Cu)
Iron ( Fe )
Magnesium ( Mg )
Note :- In this table, the metal above is the less reactive and metals below are more reactive.

Answer 2

The activity series a table in which metals are arranged in order of their decreasing reactivity.
Gold, Cooper, iron, magnesium
