Xenon forms several compounds with oxygen and fluorine. it is the most reactive non-radioactive noble gas because a. its large radius allows oxygen and fluorine to bond without being crowded. b. it has the highest electronegativity of these noble gases. c. it has the highest electron affinity of these noble gases. d. its effective nuclear charge is lower than the other noble gases. e. it has the lowest ionization energy of these noble gases.

d. its effective nuclear charge is lower than the other noble gases.

Explanation:

Xenon belongs to group O on the periodic table. Most of the elements here are unreactive.

Due to the large size of Xenon, the outermost electrons have very low effective nuclear charge. Effective nuclear charge is the effect of the positive charges of the nucleus on the electrons in orbits. This effect decreases outward as atomic shell increases.

Xenon has a very large atomic radius and there is weak a nuclear charge on the outermost electrons. The more electronegative elements would be able to attract some of its outermost electrons easily and form chemical bonds with xenon much more readily.
