Is ununbium a metal metalloid or nonmetal?

Answer 1

It is most likely a solid at room temperature, based on its atomic weight. Usually the heavier the atom is the higher its melting point. However: Uub is directly below Hg. It's possible that the same relativistic effects that make Mercury liquid at room temperature would affect Uub as well. In practical terms it doesn't matter. No more than a few atoms of Uub have ever been made, and with a half-life of 240 microseconds, the chances of ever accumulating enough of the material for its physical state to make any difference whatsoever are essentially nil.

Answer 2

It is a metal (atomic number 112). It belongs to transition metals / d-block elements.

Answer 3

It is not known but it is possible to be a noble gas.

Answer 4

It is supposed that ununpentium is a solid.
