alkali metals react violently in cold water
Among the alkali metals, the tendency to react with other substances increases form top to bottom within the group.Accompanying link shows the reaction from lithium through to cesium
Alkali earth metals react with oxygen to form basic oxides.
No.
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
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.
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
All alkali metals (group 1) and most earth-alkali metals (group 2)
Alkali metals are more reactive than alkaline earth metals.
Yes
Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.
