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.
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
All alkali metals (group 1) and most earth-alkali metals (group 2)
hydrogen gas
Yes, they do.

Alkali metals are more reactive than alkaline earth metals.
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
Basic oxides
All alkali metals (group 1) and most earth-alkali metals (group 2)
hydrogen gas
All alkali metals and alkali earth metals below calcium react vigorously with acids.
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
Some, such as the alkali metals, alkaline earth metals, and a few others do. But most don't.
halogens (group 17) and oxygen family (group 16)
They don't
alkali metals react violently in cold water
