What element is represented by the symbol 'Xe'?

The symbol 'Xe' represents the element xenon, which is a noble gas found in group 18 of the periodic table. Xenon is known for its lack of reactivity due to having a complete outer electron shell, which is characteristic of noble gases. This makes xenon useful in various applications, such as in lighting and as a general anesthetic in medicine. The other elements associated with the symbols given are chlorine, fluorine, and iodine, but none of these are represented by 'Xe'.
