The noble gases have closed-shell electronic configuration and are monoatomic gases under normal conditions. The lower boiling points of the lighter noble gases are due to weak dispersion forces between the atoms and the absence of other interatomic interactions.
Direct reaction of xenon with fluorine leads to the formation of a series of compounds with oxidation numbers +2, + 4, + 6 and + 8. XeF4 reacts violently with water to give XeO3. The compounds of xenon exhibit rich stereochemistry and their geometries can be deduced considering the total number of electron pairs in the valence shell.

Boiling Point of Noble Gases
The boiling points of noble gases generally increase with increasing atomic number. This is because the boiling point is primarily determined by the strength of intermolecular forces, and the strength of these forces increases with increasing molecular size.
Dispersion forces, also known as London forces, are the primary intermolecular forces present in noble gases. These forces arise from temporary fluctuations in electron distribution, which result in temporary dipoles. These temporary dipoles induce dipoles in neighboring atoms, leading to attractive forces between the atoms.
As the atomic size increases from helium to xenon, the number of electrons and electron shells also increases. This leads to an increase in the strength of dispersion forces between the noble gas atoms. Therefore, the boiling points of the noble gases increase as we move from helium to xenon.
Density of Noble Gases
The density of a gas is determined by its molar mass and the volume it occupies. As we move from helium to xenon, the molar mass of the noble gases increases. Therefore, the density of the noble gases generally increases from helium to xenon.
Critical Temperature of Noble Gases
The critical temperature of a substance is the temperature above which it cannot exist in the liquid state, regardless of the pressure applied. The critical temperature is primarily determined by the strength of intermolecular forces.
The critical temperature of noble gases generally increases with increasing atomic number. This is because as the atomic size increases, the strength of dispersion forces increases, leading to a higher critical temperature.
Ionization Enthalpy of Noble Gases
Ionization enthalpy is the energy required to remove an electron from an atom or ion in the gas phase. As we move from helium to xenon, the ionization enthalpy generally decreases.
This decrease in ionization enthalpy can be attributed to two main factors:
1. Increasing atomic size: As the atomic size increases, the outermost electrons are farther from the nucleus, resulting in a weaker attraction between the nucleus and the electrons. Therefore, less energy is required to remove an electron.
2. Shielding effect: As the number of electrons and electron shells increases, the inner electrons shield the outermost electrons from the full attraction of the nucleus. This also weakens the attraction between the nucleus and the outermost electrons, making it easier to remove an electron.
Therefore, the ionization enthalpy of noble gases generally decreases from helium to xenon.
