The noble gases (Group 18) are situated in the far right the the periodic table and also were previously referred to together the "inert gases" because of the truth that your filled valence shells (octets) make them incredibly nonreactive.

The sdrta.netistry Properties

Noble gases space odorless, colorless, nonflammable, and monotonic gases that have low sdrta.netical reactivity.

atom Number Element variety of Electrons/Shell
2 Helium 2
10 Neon 2,8
18 Argon 2,8,8
36 Krypton 2,8,18,8
54 Xenon 2,8,18,18,8
86 Radon 2,8,18,32,18,8

The full valence electron shells of this atoms do noble gases very stable and unlikely to form sdrta.netical bonds because they have tiny tendency to get or lose electrons. Return noble gases perform not normally react through other elements to form compounds, there room some exceptions. Xe may kind compounds through fluoride and also oxide.


Example 1: Xenon Fluorides

Xenon Difluoride ((XeF_​2))

dense white crystallized solid powerful fluorinating agent Covalent not natural fluorides steady xenon link Decomposes on contact with irradiate or water vapor straight geometry Moisture sensitive Low vapor pressure

Xenon Tetrafluoride ((XeF_4))

Figure: ~ above Oct. 2, 1963, Argonne announced the development of xenon tetrafluoride, the first simple compound of xenon, a noble gas widely believed to be sdrta.netically inert. Colorless Crystals Square planar geometry uncovered in 1963

Xenon Hexafluoride ((XeF_6))

Figure offered with permission indigenous Wikipedia. The strongest fluorinating agent Colorless solid highest coordination of the 3 binary fluorides of xenon ((XeF_2) and (XeF_4)) formation is exergonic, and also the compound is stable at normal temperatures easily sublimes into intense yellow vapors structure lacks perfect octahedral symmetry

Example 2: Xenon Oxide

Xenon Tetroxide (XeO​4)
