Question

Name the metal which has been placed
(a) at the bottom of the reactivity series
(b) at the top of the reactivity series
(c) just below copper in the reactivity series

Answer 1

Answer:

a)Gold(Au)

b)Potassium(K)

c)Mercury(Hg)

Answer 2

(a) Gold is the metal that has been placed at the bottom of the reactivity series.

(b) Potassium is the metal that has been placed at the top of the reactivity series.

(c) Mercury is the metal that has been placed just below copper in the reactivity series.

Explanation:

• Chemical reactivity series are inventive, logical and structural metal series according to their high to low reactivity.
• Metals react with various materials differ. Describes the details of metal reactions when extracting metals from ores, as well as water and acid.
• In other words, the most reactive metal is placed above and the least reactive metal is placed below. The order of intensity of reactivity is known as a reactivity series.
• The reactivity of an element decreases as it moves from top to bottom in specific reactivity series. In this series, copper, silver and gold placed at the bottom, shows that the least reactive( mostly called as noble metals).

• Reactivity of some metals are given in descending order  

        $K > Na > Ca > Mg > Al > Zn > Fe > Pb > Cu$

• Positioned potassium at the series top, making it the most reactive.
• The metal reactivity sequences can be represented in various ways, including the oxidation reaction of each metal to the corresponding metal ion.
• This is information about the reducing capability of the metal atom and the number of oxidation of metal ions.
