Ramesh dropped a metal piece $\text{'}\mathrm{A}\text{'}$ in the solution of another metal $\text{'}\mathrm{M}\text{'}$. After some time a new colourless compound $\text{'}\mathrm{N}\text{'}$ is formed.$\mathrm{A},\mathrm{M},\mathrm{N}$ respectively can be

Correct increasing order of reactivity of elements is:

Which one among the following metal is more reactive than hydrogen?

Strips of metal X were dipped into the solution of silver nitrate and zinc nitrate separately. A greyish metallic deposit was found on both strips. Metal X could be

Tick the arrangement of metals $\mathrm{Fe}$, $\mathrm{Cu}$, $\mathrm{Zn}$, $\mathrm{Ag}$ in the order of decreasing reactivity.

Which of the following set of elements is written correctly in the order of their increasing metallic character?

Given below are the following four observations of four metals.
$1.$ Metals A and B slowly react with water.
$2.$ Metal C will displace metal B from its chloride salt solution.
$3.$ Metal D will not react with dilute acids.
$4.$. Metal C will not displace metal A from its sulphate salt solution.
Their reactivity order from the most to the least reactive is:

Which one of the following four metals would be displaced from the solution of its salts by other three metals?

Which of the following metals exist in their free state in nature?

(1) Gold                                (2) Copper

(3) Aluminium                        (4) Silver

On the basis of reactivity of different metals with oxygen, water and acids as well as displacement reactions, the metals have been arranged in the decreasing order of their reactivity. This arrangement is known as activity series of metals.
The basis of reactivity is the tendency of metals to lose electrons. If a metal can lose electrons easily to form positive ions, it will react readily with other substances. Therefore, it will be a reactive metal. On the other hand, if a meal loses electrons less rapidly to form a positive ion, it will react slowly with other substances. Therefore, such a metal will be less reactive.

Which metal is less reactive than hydrogen from the given options below?

The correct reducing ability order of the metals $\mathrm{Na}, \mathrm{Ag}, \mathrm{Ca}$ and $\mathrm{Sn}$ is
