Chapter 17.2, Problem 11R

To determine

To Explain: The noble gases are unreactive.

Explanation of Solution

Introduction:

Noble gases are those gases whose chemical reactivity is very-very low because these gases are the inert gases.

Noble gases are the inert gases because they are not involved in the bond formation because the outermost shell of these gases is completely filled or it can be said that these gases do not have the incomplete valence shell which is responsible for the bond formation.

Conclusion:

Thus, noble gases are unreactive because their outermost shell is fully filled. So, it does not lose or gain the electrons and therefore, it does not involve in the bond formation.
