Question

define activity seties of metals . Arrange the metals gold , copper , iron and megnesium in order of their increase in reactivity .​

Answer 1

Answer:

The reactivity series is a series of metals, in order of reactivity from highest to lowest metal. It is used to determine the products of single displacement reactions.

According to the activity series, the order of the metals from top to bottom is magnesium, iron, copper and gold. Gold is the least reactive

Explanation:

Answer 2

Here is your answer--

Extra Information: 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:

Gold<Copper<Iron<Magnesium

Gold is least reactive whereas Magnesium is most reactive among the given set of metals.
