Until recently, the last few elements on the periodic table had the chemical symbols (now they have formal chemical symbols!):
Uub, Uut, Uuq, Uup, Uuh, Uus, and Uuo
Why did they have these temporary symbols? Why the letter U? Is there any reasoning behind the third letter? Why not:
Uua, Uub, Uuc, Uud, Uue, etc...
I was just wondering some of the history of nomenclature and the thought process behind this specific nomenclature.
