WitrynaThe noble gas elements do not react with other elements as they are less electronegative and unable to attract the lone pair of electrons from noble elements. Some of the examples of noble gas compounds are XeF2 , XeF4 , XeF6 , XeO3 , XeOF2 etc. Due to this, the noble gases form compounds with fluorine and oxygen only. round fence posts woodenWitrynaMatch the element name with the descriptive name of the group that it belongs to from the periodic table.
