The main group elements are groups 1, 2, and 13 - 18.
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!
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.

Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
The representative elements are usually called the main group elements or the Group A elements. They are located in the leftmost and middle sections of the periodic table, excluding the transition metals.
The representative, or main group elements are the elements in groups 1, 2, and 13 - 18.
Group-1 has largest atomic radius. It decreases across a period
