The list is very long for Wiki Answers; see a periodic table.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
There are no elements that are both alkali metals and halogens. Alkali metals belong to Group 1 of the periodic table and include elements like lithium, sodium, and potassium, while halogens belong to Group 17 and include elements like fluorine, chlorine, and iodine. These two groups are distinct and do not overlap.
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.

Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
There are eight classifications of elements in the periodic table. They are: Non-metals, transition metals, rare earth metals, halogens, alkali metals, alkali earth metals, other metals and inert elements.
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.

They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.
Sometimes these are called the "representative" elements.
Sodium is an Alkali metal. Elements in the center of the periodic table are transition metals.

Very reactive elements are alkali metals and halogens.
There are no elements that are both alkali metals and halogens.
