What is XENON DIFLUORIDE?
Description
Xenon difluoride is a white crystalline solid with an unpleasant odor. One of the first compounds to be prepared from "inert" gases, it was synthesized by the low-pressure photochemical reaction of xenon and fluorine by J. L. Weeks, C. L. Chernick, and M. S. Matheson in 1962. The same year, R. Hoppe and co-workers produced it via electrical discharge. XeF2 is a strong fluorinating agent.
