Alkali metals react violently when they come in contact with water
The alkali metals belonging to group 1 of the periodic table are highly reactive because of the free electron in the last shell. (Electronic configuration: ns¹)
What are alkali metals?
Metals that are strong bases and have the capacity of neutralizing strong acids are called alkali metals.
Which are the alkali metals?
Alkali metals consist of group 1 elements namely Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), Francium(Fr).
How do they react with water?
Because of high reactivity, these metals react explosively with air and water both. Because of this reason Sodium (Na), potassium are stored in Kerosene or oil so that it avoids contact with both air and water
