When an element with 115 protons in its nucleus is synthesized, will it be a metal, nonmetal, or metalloid? EXPLAIN PLEASE!

Element 115 would be at the bottom of Group 15 (5A in the old system). The top of this group are non-metals. The center of this group are metalloid and the bottom elements are metals.
That would make #115 a metal. But it is so close to the borderline with metalloids, that it is not a slam dunk answer. It will have to be tested, assuming it has a half life of more than a few microseconds.

A halogen. will no longer be able to be a metallic or a metalloid because of the fact its their solids. Non metals contains gases and drinks. Transition factors are solids. So the only the suited option answer is D, halogen, that's a gasoline decrease than regular PT situations.
