main group elements
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.

all elements that are not main group elements are metals, and since rhenium is not a main group element, it is a metal. Hope this helped!
Palladium is in group ten and is a transition metal.
