Chemistry of Group 18 Elements

The group 18 elements were once believed to be totally unreactive as a consequence of the very stable octet valence electron configurations of their atoms. Their chemistry was simple they had none  

The application of VSEPR to rationalize the structures of XeFg and XeFg is more challenging. Each Lewis structure has a lone pair on the central xenon. The VSEPR model would
