Chapter 18, Problem 35R

To determine

To Choose: The correct option.

Answer to Problem 35R

The correct option is (C).

Explanation of Solution

Introduction:

The noble gases have their outermost shell complete. So, noble gases don’t have any tendency to lose or gain electrons. Noble gases didn’t form any compound up to 1962. Later on, few gases of noble gases like Xenon, krypton was found to form few compounds with most active nonmetals like oxygen and fluorine. Therefore, noble gases were considered as least reactive in the periodic table.

Metals can form compounds with nonmetals, nonmetals can form compounds with metals as well as nonmetals and transition metals form many with nonmetals.

Therefore, the options (A), (B) and (D) are wrong. The correct answer is (C).

Conclusion:

Hence, the noble gas is least likely to react with other elements.
