As known, the chemical property for each chemical element depends on atom’s electron shells, and the quantum theory enables us to compose elements’ formulas, like this (for Sodium): Please Register or Log in to view the hidden image! Here the last electron (3s) defines Sodium’s properties. But what can we say the super-heavy chemical elements that are not created yet but probably will be in future? Let’s think about the element the Z of which is equal 180 (this probably will be created in 22-th century Please Register or Log in to view the hidden image! ). Can we write the formula for its electron shells? Can we, at least approximately, predict its chemical properties (or physical, like its color, density and etc.)? Can we state whether it will be gas, liquid or solid substance? Where can we put it in periodic table? Will not be this table overloaded eventually? Or-is it expected many elements to be so similar as Lanthanides and Actinides and to occupy such rows? Or-can there exist some super-heavy gas (Z of which will be equal to 150, 180, 200 and etc.) that will be heavier than ordinary solid substances (like ice, iron and etc.)?

Don't go past the high 80s in atomic numbers. Most past that don't have a reasonable half life anyway.
