What is the highest fluride of Uuh?

Here is a web site for the periodic table. Look up element number 116. The chemistry of Uuh should be similar to those of S, Se, Te, Po etc.

I get it as Uuh2F6 but i'm not sure if the valency for flurine should be included or if it should be just be UuhF6

I'm not connecting to your statement "if the valency for fluorine should be included". Since I know sulfur forms SF6, I would go with UuhF6.

That's good for me, thanks very very much!

You're welcome! I'm glad I could help. If you have any more questions, feel free to ask.
