That is not a very precise question. I will assume first, that you mean metallic elements, since 'metals' would include brass, bronze, pewter, and steel! The other thing that would be needed are sharp dividing lines between "very reactive" and "fairly reactive", and between metallic and semi-metallic elements. And finally, does the question mean [b]always[/b] found as ores? Copper [b]can[/b] be found as the metal in nature, but it is now very rare, and copper ores are the usual source of copper metal. Gold is nearly always found as the metal, but there is a rare gold telluride ore. Have a modern (IUPAC) periodic table in front of you for the rest of this answer. Group 1 contains only very reactive metals. Be from group 2 is arguably only fairly reactive; the other elements in this group are very reactive. Group 3, including all of the lanthanide and actinide elements, would count as very reactive, as would Ti from group 4. Zr and Hf are borderline between fairly and very reactive. Groups 5 to 12 would all count as fairly reactive metals, but Os, Ir, Pt, Au are usually found as metals rather than ores, while Ru, Rh, Pd, Ag, Hg, and Cu are sometimes found as metals. From group 13 Al and Tl count as very reactive, Ga and In as very/fairly borderline, while B is not a metal. In groups 14, 15, and 16, only Sn, Pb, Bi, and Po could be counted as metals, and they would only be fairly reactive. There are no metals in groups 17 and 18.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.

There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
potassium, nickel, carbon
Sodium, magnesium, and aluminum are examples of fairly reactive metals that are commonly found as ores in the Earth's crust. These metals can be extracted from their ores through processes such as electrolysis or chemical reactions.

Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
The alkali metals are more reactive.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
one reacts and one doesn't
Reactive metals lose electrons when being oxidised.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
