Xe, and to a limited extent Kr, form compounds, because Krypton, xenon, and radon are heavier noble gases with outer electrons that have lower ionization energies (IEs) than the heavier noble gases helium, argon, and neon. As a result, their ionization energy is reduced to a level that allows stable species to form with a few highly electronegative elements, like fluorine.
Xenon (Xe), a chemical element, is a heavy, incredibly rare gas belonging to Periodic Table Group 18 (noble gases). As a real chemical substance, it was the first noble gas discovered. Xenon is a colorless, flavorless gas that is more than 4.5 times heavier than air. There aren't many commercial applications for xenon. It is used to produce ultraviolet light in high-pressure arc lamps and photographic flash lamps, stroboscopic lamps, high-intensity arc lamps for motion picture projection, and other devices (solar simulators).
The electron's attraction to the nucleus is weaker in large-sized Xenon. Fluorine that is both extremely electronegative and tiny reacts with it (and oxygen). As a result, fluorine attracts the valence electron of Xe (or oxygen). This promotes the synthesis of compounds.
