Argon (proton number =18) is inert to any chemical reaction because
|
|
It is light
|
|
|
it is located in Group 18
|
|
|
it has achieved stable duplet electron arrangement
|
|
|
it has achieved stable octet electron arrangement
|
Explanation:
Detailed explanation-1: -The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions.
Detailed explanation-2: -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.
