Do noble gases form ionic compounds ? Why or why not

The noble gases are the least reactive of all the elements but the heavier ones do form some molecules. Helium and neon never form molecules. They have completely filled electron shells with no have-filled orbitals available for making covalent bonds and they have very high ionization energies so they don't form ions.

Explanation:

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
