Xenon formed the xenon fluorides when reacts with the fluorine atoms. So, the fluorine is very electronegative atom. So, it can react with the xenon. Xenon is a noble gas. Xenon reacts with the platinum hexafluoride and formed the complex. This reaction will occur at the temperature of $77\mathrm{K}$. Hence, xenon best reacts with the most electronegative elements.
