Alkali metals are highly reactive because they have little electronegative affinity for their own valance electrons and so donate them readily to elements and molecules with greater electronegativity, or molecules with constituent element with greater electronegativity.

halogens (group 17) and oxygen family (group 16)
The alkali metals, group 1 of the periodic table, react more and more with O2 as you descend the group. From Na down to Cs, the metals are stored in oil so that they don't form an oxide layer. If you watch videos on Youtube about these metals, you'll see the oxide layer actually form before your eyes.
They're metals that form alkaline compounds when they react with water.
Alkali metals are electropositive so they want to react with halogens which are more electronegative.
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
Alkali earth metals react with oxygen to form basic oxides.
halogens (group 17) and oxygen family (group 16)
All alkali metals (group 1) and most earth-alkali metals (group 2)
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Yes, both the alkali metals and the alkaline earth metals with react with oxygen. The alkali metals will do so rapidly even at room temperature, cesium and rubidium self-ignite on contact to air.

Alkali metals are electropositive so they want to react with halogens which are more electronegative.
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
The alkali metals in group 1 react by losing one electron.
