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, such as chlorine or iodine, will react with alkali metals to form ionic bonds by transferring electrons from the alkali metal to the halogen. This results in the formation of ionic compounds like sodium chloride or potassium iodide.
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.
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.
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
Alkali earth metals react with oxygen to form basic oxides.
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 react violently in cold water
Alkali metals react vigorously with water, producing hydrogen gas and forming alkaline solutions. They react with oxygen to form oxides, and with noble gases they can form compounds under certain conditions, although the reactivity is not as intense as with water or oxygen.
