Basic oxides
Alkali earth metals react with oxygen to form basic oxides.
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.
When alkali metals react with oxygen, they form metal oxides. This reaction is often highly exothermic and can produce heat and light. The resulting metal oxides produced will vary depending on the specific alkali metal involved.

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.
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Actually, alkali metals do react with water, producing hydrogen gas and a metal hydroxide. This reaction is often very vigorous and can even result in the metal igniting.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
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.
First group elememts are called alkali metal because they are highle reactive metal and they produce hydrogen gas as a result of any reaction. they have only one valence electron that is why they can react vigorously with any metal and they are called alkali because they form easily soluble base.
