Does this mean that the element (eg. xenon) is completely unreactive, or that it is still a tiny bit reactive?
Thanks
Oooh... and when it states that argon is used in the provision of a chemically inert atmoshpere, what does it mean?

You can get it to react (with like, magic and loads of electricity and stuff), but under normal conditions created naturally it doesnt react with anything. It can form things like XeO3 or flourides, although this was only discovered in like the 1960s (dont quote me :-s).

Argon is used in lamps to produce an inert atmosphere (specifically in bulbs). This is because when a lot of electricity passes though the fillament, if it were oxygen in the bulb and around the fillament, it would burn (i.e. react with the oxygen) and become coated in a non-conductive oxide layer (or, more likelyly the whole thing would become the oxide). By having an Argon atmosphere you stop this happening.

Bartlett discovered the first xenon compound - Xenon hexafluoroplatinate V - it nearly blew his head off when it spontaneously exploded taking his eye with it.
