Chapter 17.2, Problem 10R

To determine

To explain: The reason for noble gases to be 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. This is because the outermost shell of these gases are completely filled or it can be said that these gases do not have the valence electrons which is responsible for the bond formation.

Conclusion:

Thus, inert gases are unreactive because its outermost shell is fulfilled.
