Gonna be a pretty short project then, isn't it? :roll:

How can we know something about it if it hasn't been discovered?

well I guess all you can do is use the periodic table to 'predict' its likely properties...

You can always look for calculations on this element.
For example, there are calculations on the hydride, HUus, and the binary compounds UutUus and TlUus.

A binary compound of a transactinide? That'll be the day.
