What causes these to be so reactive is the amount of electrons in the outer most level. Each level after the first (which has 2 if full) if filled will have 8 electrons. Halogens have less than that causing it to be reactive to other elements. (i don't know how many electrons it has in the outer level) The reason why it is reactive is (depending on how many electrons it has in the outer leve) because it is either trying to gain or lose those extra electrons.

Alkali metals typically bond with elements from Group 17, known as the halogens. This is because alkali metals have one electron to donate, while halogens have one electron missing to complete their outer electron shell, creating an opportunity for a strong ionic bond to form between the two groups.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
Halogens.
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
An ionic bond is formed by electron transfer between alkali metals and halogens.

The elements of the 1st GROUP of the periodic table are called alkali metals. The elements of the 17th GROUP of the periodic table are called halogens. Alkali metals are soft metals whereas halogens are non-metals.

The most active metals are alkali metals.The most active nonmetals are halogens.
Examples: alkali metals, alkali earth metals, noble gases, platinum metals, halogens, etc.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
