A new chemical element is recognised

The periodic table grows by one to 112, to the bane of chemistry and physics students around the world.

From New Scientist:

For years, the space next to [Roentgenium at position 111] has been unceremoniously occupied by the letters Uub, which stand for ununbium, the Latin word for 112 that has stood as a placeholder.

That place is now filled, all it needs is a name. How about onehundredweightium?
