Question

Argon which is the noble gas is an active element.
A.True
B.False

Answer 1

General electronic configuration of valence shells of noble gases is $n{s^2}n{p^6}$(except Helium) due to their complete configuration of valence shell, they are placed In zero group. All of the elements of this group are called inert gases because they can’t react with any other element due to their complete configuration. But in the laboratory the compound of these elements can be found under chemical processes.

Complete step by step answer:
Argon, one of the members of zero group/noble gases of atomic number $18$. And have octet electronic configuration $\left( {2,8,8} \right)$. Which shows that it has no valence electron to pair with any other element Hence it is an inert gas not an active element. The symbolic representation of argon is . and placed in the group $18$ of the modern periodic table. The electronic configuration of argon is written as - $Ar = 1{s^2}2{s^2}2{p^6}3{s^2}3{p^6}$
The name “Argon” is derived from the Greek word argos i.e. neuter singular (meaning lazy or inactive). As a reference to the fact that the element undergoes almost no chemical reactions.
The complete octet in the outer atomic shell makes argon stable and resistant to bonding with other elements. As the valence shell of noble gases are complete, thus they do not show a tendency to gain electrons hence the electron affinity of the noble gases is zero.

Note:
Argon is mostly used as an inert shielding gas in welding. Argon-oxygen mixture is used for producing inert atmosphere in electric bulbs. It helps in increasing the life of filament. It is also used for filling radio-valves.
