Q
Atomic radius
IE
EGE
Atomicity
Solubility in water
Low MP and BP. Why?
Diffuses through what type of lab materials?
A
Increases down the group
Very high. Decreases down the group
Large and +ve due to stable EC.
Monoatomic
Sparingly soluble
Because of only dispersion force
Rubber and glass.
3
Q
Reactions of G18
Hydrolysis of XeF2
Hydrolysis and partial hydrolysis of XeF6
A
XeF2 + H2O –> Xe + HF + O2
XeF6 + 3H2O –> XeO3 + HF
And
XeF6 + H2O (partial) –> XeOF4 + 2HF
XeF6 + 2H2O(partial) –> XeO2F2 + 4HF
