Boiling point oxygen family elements

Xenon, Xe, is a gaseous, nonmetallic element from family eight. It is a colorless, odorless gas or liquid. It is nonflammable and nontoxic at standard temperatnres and pressnres, but is an asphyxiant and will displace oxygen in the air. The boiling point is -162°F, and the vapor density is 05.987, which is heavier than air. Xenon is chemically unreactive however, it is not completely inert. The fonr-digit UN identification number is 2036 for the compressed gas and 2591 for the cryogenic liqnid. Xenon is used in luminescent tubes, flash lamps in photography, lasers, and as an anesthesia.
