Noble Gases (group 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!
Hydrogen is the only element in Group 1 that is not a metal. The other heavier metals in group one, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are all called alkali metals, which are highly reactive since they do not have a full valence shell.
Almost all of the non-metals are brittle when solid. For example, sulfur.
There are few different groups of elements. The main groups would be the metals, non mental and metalloids.
Group 13 contain aluminium, gallium, indium, thallium, ununtrium (metals) and boron (nonmetal).
Oxygen is classified as a non-metal element in the periodic table. It is part of the chalcogen group, which is a group of reactive non-metals.

Non metals
Group 1-12 (all metals). Group 13-16 contains metals, metalloids as well as non-metals.
Lead is a transition state element, and all of the transition state elements are metals; there are no non-metal elements in the transition state.
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
non metals
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
non-metal
Almost all of the non-metals are brittle when solid. For example, sulfur.
All elements in Ammonium nitride are Non-metals, i.e. Hydrogen and Nitrogen are non-metals
