there are alkali metals that are the most reactive metals on the Periodic Table and halogens which are the most reactive nonmetals
they are very reactive, because when the elements are spread go to facebook . com
Being very reactive these elements react quickly and form compounds.
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.
Group 1 the Alkali Metals and Group 2 the Alkaline Metals. Group 1 is more reactive than Group 2.The three major reactive groups of elements are the alkali metals, Alkaline Earth and halogens (these groups are labeled 1 or IA, 2 or IIA, and 17 or VIIIB respectively)
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
groups 11 and 12
The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
Causes: very low ionization potential, very great electropositivity.
Groups 1 and 2 are highly reactive.It consist of alkali metals and alkaline earth metals.They react violently with water.
Yes. Lithium is very reactive to other elements.

all the elements of group 18 are Nobel gases. They are very very less reactive.
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Noble Gases
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Noble gases are least reactive because they have a full shell
