The most reactive metals are the alkali metals in group 1a.
It means metals that are highly reactive. It's one of the most self-evident pieces of terminology in all of chemistry. Perhaps you were trying to ask which metals are considered "highly reactive", which is a separate question, and one that to some extent depends on your definitions, but would certainly at minimum include all the alkali metals, maybe the alkaline earth metals, and possibly a few selected others (aluminium, for example... we don't usually think of aluminium as "highly reactive" because it immediately forms a thin transparent protective layer of aluminium oxide when exposed to air, but without that layer, it is indeed pretty reactive).
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.

The alkali metals are more reactive.
No. The alkali and alkaline earth metals are very reactive.
Alkali metals are the most reactive metals.

Highly reactive metals with one valence electron are known as Alkali metals.
Alkali metals are very reactive metals.
alkali metals
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.
