제논 개요

Unusual among the noble gases for its measurable chemistry, xenon (Xe) forms stable compounds with fluorine and oxygen despite belonging to group 18. Element 54 lies in period 5 of the p-block, with an atomic mass of 131.29, the closed-shell configuration [Kr] 4d¹⁰ 5s² 5p⁶, and a Pauling electronegativity of 2.6. A dense, colorless gas at standard conditions, xenon produces a brilliant white light when electrically excited, which makes it valuable in photographic flash lamps and high-intensity arc lamps. It also serves as a general anesthetic. Its large, polarizable electron cloud allows the bonding that lighter noble gases resist.
