the alkali metals are the most reactive because they only have 1 electron in their outer shell, so they are 'ready' to lose it really easily.
The most reactive groups are alkali metals and halogens.
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
The alkali metals in column 1 of most wide-form periodic tables.
The alkali metals are the most reactive (Li, K, Na, Rb, Cs, Fr).
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
The most reactive groups are alkali metals and halogens.

Alkali metals
The alkali metals in column 1 of most wide-form periodic tables.
Alkali metals in the first group compose the most reactive family of metals.
The alkali metals are the most reactive (Li, K, Na, Rb, Cs, Fr).
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
The first two groups--alkali metals and the alkali earth metals--are the most reactive.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
Cesium is the most chemically reactive metal
The most reactive metals are the alkali metals in group 1a.
