For example halogens easily react with alkali metals because both are very reactive; compounds are with ionic bonds.
Metals: alkaline metals Nonmetals: halogens
The nonmetals in Group 7A are called halogens. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive elements that tend to form salts when they react with metals.
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 more common name for group 7 metals is the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form salts with metals.
The halogens.
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
You can identify alkali metals in Group 1, alkaline earth metals in Group 2, transition metals in Groups 3-12, halogens in Group 17, and noble gases in Group 18 on the periodic table. Each group has characteristic properties that define them, such as valence electrons and reactivity, which can help in their identification.
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.
