The noble gases have close shell electronic configuration and are monoatomic gases under normal conditions. The low boiling points of the lighter noble gases are due to weak dispersion forces between the atoms and the absence of other inter atomic interactions. The direct reactions of xenon with fluorine leads to a series of compounds with oxidation number `+2, +4 " and" +6. XeF_(4)` reacts violently with water to give`XeO_(3)`. The compounds of xenon exhibit stereochemistry and their geometries can be deduced considering the total number of electrons in valence shell
Argon is used in are welding because of its.
A. ability to lower reactivity of metals
B. ability to lower the melting point of the solid
C. flammability
D. high calorific value
