Hi Michael,

Perhaps it is more a matter of patience than anything else.

When in college one of the professors had a hobby to trace errors in text books back to the original source. In one case the original error had been "plagerized" from text book to text book for over 50 years! For over a hundred years the conventional wisdom was that the inert gases did not form compounds with other elements. Yet not too long ago a graduate student mixed xenon and fluorine gases together and produced a solid compound xenon tetrafluoride. This led to several other xenon compounds like xenic acid.
