Chapter 7, Problem 53A

Interpretation Introduction

Interpretation:

The reason for the noble gases to not form chemical bond needs to be explained.

Concept introduction:

The periodic table has many groups based on the similarity in their properties based on their atomic numbers. Noble gas belongs to group 18 of periodic table. The elements are mostly Helium, Neon, Argon, Krypton, Xenon, Radon.

Answer to Problem 53A

Noble gases does not form chemical bonds as its shells are all full and will not accept or gain electrons.

Explanation of Solution

Noble gases belong to Group 18 of the periodic table. The elements present in this group is

Helium : ${\text{1s}}^2$

Neon : $\left[\text{He}\right]2{\text{s}}^{\text{2}}2{\text{p}}^6$

Argon : $\left[\text{Ne}\right]3{\text{s}}^{\text{2}}{\text{3p}}^6$

Krypton : $\left[\text{Ar}\right]{\text{ 4s}}^{\text{2}}{\text{3d}}^{10}{\text{4p}}^6$

Xenon : $\left[\text{Kr}\right]{\text{ 5s}}^{\text{2}}{\text{4d}}^{10}{\text{5p}}^6$

Radon : $\left[\text{Xe}\right]6{\text{s}}^{\text{2}}{\text{4f}}^{14}{\text{5d}}^{10}{\text{6p}}^6$

On observing the valence electrons of all the elements, it is noticed that all the shells are filled and there is no vacancy. These elements will not form compounds with other elements.

Conclusion

Noble gases does not form chemical bonds as its shells are all full and will not accept or gain electrons.
