The noble gases (Group 18) are situated in the much right of the regular table and were previously referred to together the "inert gases" due to the truth that your filled valence shells (octets) make them very nonreactive.




You are watching: Which of the following group 18 elements would be most likely to form a compound with fluorine

The mmsanotherstage2019.comistry Properties

Noble gases space odorless, colorless, nonflammable, and also monotonic gases that have low mmsanotherstage2019.comistry reactivity.

atomic Number Element number 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 these atoms do noble gases incredibly stable and also unlikely to form mmsanotherstage2019.comical bonds because they have little tendency to get or shed electrons. Return noble gases do not normally react v other aspects to type compounds, there space some exceptions. Xe may type compounds v fluoride and oxide.


Example 1: Xenon Fluorides

Xenon Difluoride ((XeF_​2))

thick white crystallized solid an effective fluorinating certified dealer Covalent not natural fluorides stable xenon link Decomposes on call with light or water vapor linear geometry Moisture perceptible Low vapor pressure

Xenon Tetrafluoride ((XeF_4))

Figure: top top Oct. 2, 1963, Argonne announced the production of xenon tetrafluoride, the first simple link of xenon, a noble gas widely thought to it is in mmsanotherstage2019.comically inert. Colorless Crystals Square planar geometry uncovered in 1963

Xenon Hexafluoride ((XeF_6))

Figure offered with permission native Wikipedia. Strongest fluorinating certified dealer Colorless solid greatest coordination that the 3 binary fluorides that xenon ((XeF_2) and (XeF_4)) formation is exergonic, and also the link is stable at regular temperatures conveniently sublimes right into intense yellow vapors structure lacks perfect octahedral symmetry
